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.
