scsi: qla2xxx: Select qpair depending on which CPU post_cmd() gets called

Browse source 
[ Upstream commit 1d201c81d4 ]

In current I/O path, Tx and Rx may not be processed on same CPU. This may
lead to thrashing and optimum performance may not be achieved.

Pick qpair such that Tx and Rx are processed on same CPU.
