ACPI: Properly clear flags on false-positives and send uevent on sudden unplug
Some devices emit a ACPI_NOTIFY_DEVICE_CHECK while physically unplugging
even if the software undock has already been done and dock_present() check
fails. However, the internal flags need to be cleared (complete_undock()).
Also, even notify userspace if the dock station suddently went away
without proper software undocking.
This happens on a Acer TravelMate 3000
