RDMA/mlx5: Clear old rate limit when closing QP

Browse Source 
[ Upstream commit c8973df2da ]

Before QP is closed it changes to ERROR state, when this happens
the QP was left with old rate limit that was already removed from
the table.

Fixes: 7d29f349a4 ("IB/mlx5: Properly adjust rate limit on QP state transitions")
