net: core: add member wol_enabled to struct net_device

Browse Source 
Add flag wol_enabled to struct net_device indicating whether
Wake-on-LAN is enabled. As first user phy_suspend() will use it to
decide whether PHY can be suspended or not.

Fixes: f1e911d5d0 ("r8169: add basic phylib support")
Fixes: e8cfd9d6c7 ("net: phy: call state machine synchronously in phy_stop")
