r8169: fix RTL8117 Wake-on-Lan in DASH mode

Browse Source 
Wake-on-Lan does currently not work for r8169 in DASH mode, e.g. the
ASUS Pro WS X570-ACE with RTL8168fp/RTL8117.

Fix by not returning early in rtl_prepare_power_down when dash_enabled.
While this fixes WoL, it still kills the OOB RTL8117 remote management
BMC connection. Fix by not calling rtl8168_driver_stop if WoL is enabled.
