RDMA/mlx5: Avoid memory leak in case of XRCD dealloc failure

Browse Source 
[ Upstream commit b081808a66 ]

Failure in XRCD FW deallocation command leaves memory leaked and
returns error to the user which he can't do anything about it.

This patch changes behavior to always free memory and always return
success to the user.
