Original code would inadvertanly place I/Os on the default
request-queue. Also, correctly pass in the proper MSI-X vector
during response-queue initialization.

Following changes have been made.
1. qla_hw_data structure holds an array for request queue pointers,
and an array for response queue pointers.
2. The base request and response queues are created by default.
3. Additional request and response queues are created at the time of vport
creation. If queue resources are exhausted during vport creation, newly
created vports use the default queue.
4. Requests are sent to the request queue that the vport was assigned
in the beginning.
5. Responses are completed on the response queue with which the request queue
is associated with.

Following changes have been made to the qla2xxx FC driver in
preparation for the multi- queue and future SR IOV hardware.
1. scsi_qla_host structure has been changed to contain scsi host
specific data only.
2. A new structure, qla_hw_data is created to contain HBA specific
hardware data.
3. Request and response IO specific data strucures are created.
4. The global list of fcports for the hba is not maintained anymore,
instead a fcport list is construted on per scsi_qla_host.

Minor fixes addressing:
- rport managements during vport deletion.
- acquire proper physical-ha during qla24xx_abort_command() and
qla24xx_queuecommand()
- do not needlessly acquire the pha for non-NPIV capable ISPs.

loop-resync.
There were several issues here, one, during RSCN handling if a
follow-on RSCN occurred (within interrupt context) the DPC thread
could inadvertantly leave the fcport in a stale lost state.
Secondly, scheduled rport removal is handled exclusively by the
'parent' DPC thread, so wake up the proper thread. Finally,
process vport loop-resync's only when the vport has in an
"active" state (ID acquired).

Upon having configuration changes on vports only, the driver
handles SCR regardless physical port state and, in turn, it
results mailbox error as below:
Mar 20 11:24:20 dl585 kernel: qla2x00_mailbox_command(9): **** FAILED. mbx0=4005, mbx1=1, mbx2=8100, cmd=70 ****
With the changes, driver checks physical port loop_state and make
sure the port is ready to take commands.
