RDMA: Introduce and use GID attr helper to read RoCE L2 fields
Instead of RoCE drivers figuring out vlan, smac fields while working on
QP/AH, provide a helper routine to read the L2 fields such as vlan_id and
source mac address.
This moves logic from mlx5 driver to core for wider usage for RoCE ports.
This is a preparation patch to allow detaching netdev in subsequent patch.
