RDMA/mlx5: Clear old rate limit when closing QP
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: 7d29f349a4b9 ("IB/mlx5: Properly adjust rate limit on QP state transitions") Signed-off-by: Rafi Wiener <rafiw@mellanox.com> Signed-off-by: Oleg Kuporosov <olegk@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Link: https://lore.kernel.org/r/20191002120243.16971-1-leon@kernel.org Signed-off-by: Doug Ledford <dledford@redhat.com>
