Ryan Moeller 43efd5625b Avoid taking global lock to destroy zfsdev state ... We have exclusive access to our zfsdev state object in this section until it is invalidated by setting zs_minor to -1, so we can destroy the state without taking a lock if we do the invalidation last, after a member to ensure correct ordering. While here, strengthen the assertions that zs_minor is valid when we enter.
