r8169: call netif_napi_del at errpaths and at driver unload

commit ad1be8d345416a794dea39761a374032aa471a76 upstream.

when register_netdev fails, the init'ed NAPIs by netif_napi_add must be
deleted with netif_napi_del, and also when driver unloads, it should
delete the NAPI before unregistering netdevice using unregister_netdev.
