[PATCH v1 1/2] Regression fix: Fix pending IOs counter per reply queue

[Ranjan Kumar <ranjan.kumar@broadcom.com>]

Commit 199510e33dea ("scsi: mpi3mr: Update consumer index of
reply queues after every 100 replies") introduced a regression
with Per reply queue pending IOs counter was wrongly decremented
leading to counter getting negative.

Fixed the issue by dropping the extra atomic decrement for
pending IOs counter.
