scsi: qla2xxx: Fix command flush during TMF

Browse source

For each TMF request, driver iterates through each qpair and flushes
commands associated to the TMF. At the end of the qpair flush, a Marker is
used to complete the flush transaction. This process was repeated for each
qpair. The multiple flush and marker for this TMF request seems to cause
confusion for FW.

Instead, 1 flush is sent to FW. Driver would wait for FW to go through all
the I/Os on each qpair to be read then return. Driver then closes out the
transaction with a Marker.
