LOLi 97f8d7961e Fix zvol_state_t->zv_open_count race 
5559ba0 added zv_state_lock to protect zvol_state_t internal data:
this, however, doesn't guard zv->zv_open_count and
zv->zv_disk->private_data in zvol_remove_minors_impl().

Fix this by taking zv->zv_state_lock before we check its zv_open_count.
