net/mlx4_core: Prevent VF from changing port configuration
Added wrapper to the ACCESS_REG command for handling guest HW
registers access, preventing write operations, but do allow reads.
This will prevent SRIOV guests to change port PTYS configuration,
such as speed/advertised link modes.
Fixes: adbc7ac5c15e ('net/mlx4_core: Introduce ACCESS_REG CMD [...]')
