[SCSI] mpt2sas : PPC (power pc) endian bug fix's

(1) EEDP(End to End data protection) was not working. This was due to not
setting EEDP BlockSize and Flags to little endian format in the message
frame.
(2) Some expander sysfs attributes were not getting set properly.  The sas
format was not getting set due to endian issues with sas_format field in the
struct rep_manu_reply. Since sas_format was not set properly, the
component_vendor_id, component_revision_id, and component_id were not set.
(3) In _transport_smp_handler: we don't need to convert the smid from little
endian to cpu prior to calling mpt2sas_base_free_smid, because its allready
in cpu format. (4) Some loginfos and ioc status were not xonverted from
little endian to cpu.
