net: aquantia: oops when shutdown on already stopped device
In case netdev is closed at the moment of pci shutdown, aq_nic_stop gets called second time. napi_disable in that case hangs indefinitely. In other case, if device was never opened at all, we get oops because of null pointer access. We should invoke aq_nic_stop conditionally, only if device is running at the moment of shutdown.
