Subject: RDMA/mlx5: Fix legacy IPoIB QP initialization
Patch-mainline: v5.8-rc5
Git-commit: f81b4565c1108fb954f344e6b4a153c8189e57fe
References: jsc#SLE-15175

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")
