r8169: re-configure WOL settings on resume from hibernation

So far we don't re-configure WOL-related register bits when waking up
from hibernation. I'm not aware of any problem reports, but better
play safe and call __rtl8169_set_wol() in the resume() path too.
To achieve this move calling __rtl8169_set_wol() to
rtl8169_net_resume() and rename the function to rtl8169_runtime_resume().
