[PATCH 2/2] r8169: WoL fixes

["Bruno Prémont" <bonbons@linux-vserver.org>]

Since recent kernel (2.6.26 or 2.6.27) the PCI wakeup functions are
influenced by generic device ability and configuration when enabling
PCI-device triggered wake-up.

This patch causes WoL setting to enable/disable device's wish to
be permitted to wake-up the host when changing WoL options and
also during device probing.

Without this patch one has write 'enabled' to
  /sys/bus/pci/devices/0000:02:08.0/power/wakeup
