net/mlx5: Move SF dev table notifier registration outside the PF devlink lock
This completes the previous patches by moving notifier registration for
SF dev tables outside the devlink locked critical section in
mlx5_init_one() / mlx5_uninit_one() and into the mlx5_mdev_init() /
mlx5_mdev_uninit() functions.
This is only done for non-SFs, since SFs do not have a SF HW table
themselves.
After this patch, notifiers can grab the PF devlink lock (soon to be
necessary) without creating a locking cycle.
