3.18-stable review patch. If anyone has any objections, please let me know.
------------------ From: Majd Dibbiny <m...@mellanox.com> [ Upstream commit 31fde034a8bd964a5c7c1a5663fc87a913158db2 ] The UMR's QP is created by calling mlx5_ib_create_qp directly, and therefore the send CQ and the recv CQ on the ibqp weren't assigned. Assign them right after calling the mlx5_ib_create_qp to assure that any access to those pointers will work as expected and won't crash the system as might happen as part of reset flow.
