eth: gve: add missing netdev locks on reset and shutdown paths

Browse Source 
All the misc entry points end up calling into either gve_open()
or gve_close(), they take rtnl_lock today but since the recent
instance locking changes should also take the instance lock.

Found by code inspection and untested.

Fixes: cae03e5bdd ("net: hold netdev instance lock during queue operations")
