[PATCH rdma-rc] RDMA/mlx5: Fix legacy IPoIB QP initialization

[Leon Romanovsky <leon@kernel.org>]

From: Leon Romanovsky <leonro@mellanox.com>

Legacy IPoIB sets IB_QP_CREATE_NETIF_QP QP create flag and because
mlx5 doesn't use this flag, the process_create_flags() failed to
create IPoIB QPs.

Fixes: 2978975ce7f1 ("RDMA/mlx5: Process create QP flags in one place")
