Patrisious Haddad cf32affe6f RDMA/mlx5: Fix error flow upon firmware failure for RQ destruction
[ Upstream commit 5d2ea5aebb ]

Upon RQ destruction if the firmware command fails which is the
last resource to be destroyed some SW resources were already cleaned
regardless of the failure.

Now properly rollback the object to its original state upon such failure.

In order to avoid a use-after free in case someone tries to destroy the
object again, which results in the following kernel trace:
refcount_t: underflow; use-after-free.
