net/mlx5: implement max_sfs parameter

Implement max_sfs generic parameter to allow users to control the total
light-weight NIC subfunctions that can be created using devlink instead
of external vendor tools. A value of 0 will effectively disable creation
of new subfunction devices. A warning is sent to user-space via extack
(returning extack without error code is interpreted as a warning by
user-space tools). The maximum value is capped at U16_MAX.
