Subject[PATCH 3.16 124/212] IB/mlx5: Return error for unsupported signature type
3.16.44-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Leon Romanovsky <leonro@mellanox.com>

commit 12bbf1ea7e3b35892dbb8636b978160bc9576b61 upstream.

In case of unsupported singature, we returned positive
value, while the better approach is to return -EINVAL.

In addition, in this change, the error print is enriched
to provide an actual supplied signature type.

Fixes: e6631814fb3a ("IB/mlx5: Support IB_WR_REG_SIG_MR")
