Subject: RDMA/mlx5: Avoid memory leak in case of XRCD dealloc failure
Patch-mainline: v4.16-rc1
Git-commit: b081808a66345ba725b77ecd8d759bee874cd937
References: bsc#1046305 FATE#322943
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.
