net/mlx5: Lag, use lag lock
Use a lag specific lock instead of depending on external locks to
synchronise the lag creation/destruction.
With this, taking E-Switch mode lock is no longer needed for syncing
lag logic.
Cleanup any dead code that is left over and don't export functions that
aren't used outside the E-Switch core code.
