sungem: Fix WakeOnLan

[ Upstream commit 5a8887d3 ]

WakeOnLan was broken in this driver because gp->asleep_wol is a 1-bit
bitfield and it was being assigned WAKE_MAGIC, which is (1 << 5).
gp->asleep_wol remains 0 and the machine never wakes up.  Fixed by casting
gp->wake_on_lan to bool.  Tested on an iBook G4.
