[PATCH] net/mlx5: fix Rx Hash queue resource release in sample flow

[Jiawei Wang]

While the queue/rss action was added to sample action lists,
the rx hash queue resource was allocated in the sample action
translation to create the sample DR action later.

While there's a failure in the flow creation, the Rx hash queue
resource of the sample action list was destroyed in the wrong place.

This patch adds the checking to release the Rx hash queue
resource after the sample action release, to avoid one more
extra release if there's a failure.
