Bubble-up retval from iscsi_update_param_value() and
iscsit_ta_authentication().
Other very small retval cleanups.

Neither "acceptor_values" nor "proposer_values" can be NULL here when
scanning the value lists for incoming iSCSI login parameters such as
HeaderDigest=CRC32C,None.
Smatch complains because we are not allowed to pass NULL pointers to
strchr(). Also I removed a second later check for "!acceptor_values"
because it gets checked on the next line in the do while condition.

local_right_val was an obvious case, tmp_ptr is also write-only, but
evades the compiler by being passed to simple_strtoul as char **endp.

This patch makes iscsi-target explictly disable OFMarker=Yes and IFMarker=yes
parameter key usage during iscsi login by setting IFMarkInt_Reject and
OFMarkInt_Reject values in iscsi_enforce_integrity_rules() to effectively
disable iscsi marker usage. With this patch, an initiator proposer asking
to enable either marker parameter keys will be issued a 'No' response, and
the target sets OFMarkInt + IFMarkInt parameter key response to 'Irrelevant'.
With markers disabled during iscsi login, this patch removes the problematic
on-stack local-scope array for marker intervals in iscsit_do_rx_data() +
iscsit_do_tx_data(), and other related marker code in iscsi_target_util.c.
This fixes a potentional stack smashing scenario with small range markers
enabled and a large MRDSL as reported by DanC here:

We leak memory if the allocations for 'new_param->name' or
'new_param->value' fail in iscsi_target_parameters.c::iscsi_copy_param_list()
We also do a lot of variable assignments that are completely pointless
if the allocations fail.
So, let's move the allocations before the assignments and also make
sure that we free whatever was allocated to one if the allocation fail.
There's also some small CodingStyle fixups in there (curly braces on
both branches of if statement, only one variable per line) since I was
in the area anyway. And finally, error messages in the function are
put on a single line for easy grep'abillity.

The Linux-iSCSI.org target module is a full featured in-kernel
software implementation of iSCSI target mode (RFC-3720) for the
current WIP mainline target v4.1 infrastructure code for the v3.1
kernel. More information can be found here:
http://linux-iscsi.org/wiki/ISCSI
This includes support for:
* RFC-3720 defined request / response state machines and support for
all defined iSCSI operation codes from Section 10.2.1.2 using libiscsi
include/scsi/iscsi_proto.h PDU definitions
* Target v4.1 compatible control plane using the generic layout in
target_core_fabric_configfs.c and fabric dependent attributes
within /sys/kernel/config/target/iscsi/ subdirectories.
* Target v4.1 compatible iSCSI statistics based on RFC-4544 (iSCSI MIBS)
* Support for IPv6 and IPv4 network portals in M:N mapping to TPGs
* iSCSI Error Recovery Hierarchy support
* Per iSCSI connection RX/TX thread pair scheduling affinity
* crc32c + crc32c_intel SSEv4 instruction offload support using libcrypto
* CHAP Authentication support using libcrypto
* Conversion to use internal SGl allocation with iscsit_alloc_buffs() ->
transport_generic_map_mem_to_cmd()
