Subject: [ 73/84] r8169: call netif_napi_del at errpaths and at driver unload

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Devendra Naga <devendra.aaru@...il.com>

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.
