Subject: [PATCH net-next 3/3] sh_eth: Use async pm_runtime_put()

There is no stringent need to power down the device immediately after a
register read, or after a failed open.  Relax power down handling by
replacing calls to synchronous pm_runtime_put_sync() by calls to
asynchronous pm_runtime_put().
