net/mlx5: fix Rx queue release of resources

  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: 69abf7b1db4a ("net/mlx5: create advanced RxQ using new API")
