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: c1c98501 ("IB/mlx4: Add support for steerable IB UD QPs")
