mlx4: In RoCE allow guests to have multiple GIDS
The GIDs are statically distributed, as follows: PF: gets 16 GIDs VFs: Remaining GIDS are divided evenly between VFs activated by the driver. If the division is not even, lower-numbered VFs get an extra GID. For an IB interface, the number of gids per guest remains as before: one gid per guest.
