[PATCH rdma-rc 2/2] RDMA/mlx5: Fix remote gid value in query QP

[Leon Romanovsky <leon@kernel.org>]

From: Maor Gottlieb <maorg@mellanox.com>

Remote gid is not copied to the right address. Fix it by using
rdma_ah_set_dgid_raw to copy the remote gid value from the QP
context on query QP.

Fixes: 70bd7fb87625 ("RDMA/mlx5: Remove manually crafted QP context the query call")
