RDMA/mlx4: Return missed an error if device doesn't support steering
[ Upstream commit f4e56ec4452f48b8292dcf0e1c4bdac83506fb8b ]
The error flow fixed in this patch is not possible because all kernel
users of create QP interface check that device supports steering before
set IB_QP_CREATE_NETIF_QP flag.
Fixes: c1c98501121e ("IB/mlx4: Add support for steerable IB UD QPs")
