ixgbe: only enable WoL for magic packet by default

Martin Wilck <martin.wilck@ts.fujitsu.com> reported that systems using
the ixgbe-driver that were capable of WoL were rebooting almost as soon
as they were shut down.  This is because the default WoL settings
enabled magic packet, broadcast, unicast, and multicast.

Other Intel devices seem to use the stored eeprom value for initial WoL
capabilities.  The 82578DM (e1000e) and 82576 (igb) the devices I looked
at had only the magic packet enabled in the eeprom, so that seems
appropriate on ixgbe-based devices as well.  I set the WoL options on my
82578DM to be the same default as the ixgbe devices (umbg) and saw the
same as Martin -- almost as soon as my box shutdown, it booted again.

This patch changes the default to only be the magic packet.  This is the
same as the default for most Intel and non-Intel hardware currently
upstream.
