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.
