[dpdk-dev] [PATCH] net/mlx5: fix Rx queue release assertions

[Matan Azrad]

In debug mode, there is assertion to validate the CQ object before the
release.

Wrongly, the assertion is done for any type of RX queue even if it
doesn't use CQ at all, for example in hairpin Rx queue.

Ignore CQ assertion when hairpin queue is released.
