[dpdk-dev] [PATCH] compress/qat: fix error counter in dequeue errors

[Tomasz Jozwiak]

This patch increments error counter (stats.dequeue_err_count)
in case of any error detection during qat_comp_process_response
function.

Fixes: 3cc14fc48e35 ("compress/qat: check that correct firmware is in use")
Fixes: 32842f2a6d7d ("compress/qat: create FW request and process response")
Cc: stable at dpdk.org
