r8169: fix LED-related deadlock on module removal
Binding devmledclassdev_register() to the netdev is problematic because on module removal we get a RTNL-related deadlock. Fix this by avoiding the device-managed LED functions.
Note: We can safely call ledclassdevunregister() for a LED even if registering it failed, because ledclassdevunregister() detects this and is a no-op in this case.
