Function rxq_release_rq_resources() releases resources of RQ object
created by DevX API.

This patch updates this function to properly clear the released
resources, to avoid repeated release of the same resource.

Fixes: 13f4e1b32137 ("net/mlx5: create advanced RxQ using new API")

v3: Use adequate 'Fixes' reference.
