mlx5: Fix incorrect wc pkey_index assignment for GSI messages
Since patch series "Demux IB CM requests in the rdma_cm module" the P_Key index is taken from the work completion rather than the message itself. The HCA provides us with the message P_Key. In order to provide the P_Key index, we need to look it up. Given that this is relevant only for GSI messages (session establishments) which is less performance critical, micro-optimize against the GSI (is_qp1) branch. Fixes: 4c21b5bcef73 ("IB/cma: Add net_dev and private data checks to RDMA CM") Signed-off-by: Sagi Grimberg <sagig@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
