[PATCH V2 mlx5-next 12/13] RDMA/mlx5: Add vport metadata matching for IB representors

[Saeed Mahameed <saeedm@mellanox.com>]

From: Jianbo Liu <jianbol@mellanox.com>

If vport metadata matching is enabled in eswitch, the rule created
must be changed to match on the metadata, instead of source port.
