[PATCH rdma-rc 05/10] IB/mlx5: Fix returned values of query QP

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Noa Osherovich <noaos-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

Some variables were not initialized properly: max_recv_wr,
max_recv_sge, max_send_wr, qp_context and max_inline_data.

Fixes: e126ba97dba9 ('mlx5: Add driver for Mellanox Connect-IB...')
