Tej Parkash a24058f9c2 [SCSI] qla4xxx: Fixed request queue count manipulation on response path 
Issue:
Request queue count holds the information about free space in request queue
which has to be manipulated based on request in and out pointer.
But in driver response path, this count was incremented unconditionally,
which could move req_in pointer beyond req_out pointer.
This scenario leads fw hang during IO.

Solution:
Request queue count manipulation has to be done in IO path only, keeping
req_in and req_out pointer two IOCB count away
