4.14-stable review patch. If anyone has any objections, please let me know.

From: Leon Romanovsky <leonro@xxxxxxxxxxxx>
[ Upstream commit b081808a66345ba725b77ecd8d759bee874cd937 ]
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.
Fixes: e126ba97dba9 ("mlx5: Add driver for Mellanox Connect-IB adapters")
