Don't hold state lock while detaching network device instance in mlx4en(4).

It can happen during shutdown that the lock will recurse when the mlx4en(4)
instance is part of a lagg interface. Call ether_ifdetach() unlocked.

Backtrace:
panic(): _sx_xlock_hard: recursed on non-recursive sx &mdev->state_lock
