ACPI: Set flag DOCK_UNDOCKING when triggered via sysfs
begin_undock() is only called when triggered via a acpi notify handler (pressing the undock button on the dock station), but complete_undock() is always called after the eject. So if a undock is triggered through a sysfs write, the flag DOCK_UNDOCKING has to be set for the dock station, too. Otherwise this will freeze the system hard.
