[dpdk-dev] [PATCH] common/qat: fix stats update

[Adam Dybkowski]

This patch fixes enqueued and dequeued count statistics that should
contain the numer of operations enqueued by the end user app
instead of the total number of QAT requests - bigger in case of
a multiple-request dynamic Huffman compression operation.

Fixes: c13cecf60f12 ("compress/qat: support IM buffer too small operation")
