macvlan: remove one synchronize_rcu() call
When one macvlan device is dismantled, we can avoid one
synchronize_rcu() call done after deletion from hash list, since caller
will perform a synchronize_net() call after its ndo_stop() call.
Add a new netdev->dismantle field to signal this dismantle intent.
Reduces RTNL hold time.
