When receiving an undock request, walk the list of dependant devices
and pull their _EJ0 knobs before undocking. This ejects any dependant
devices (if necessary) before actually undocking.
Without this, the usb hub in my X6 gets upset when it's suddenly kicked
off the system without warning, and upon redocking it attaches as uberry.
Now it's behaving as it should.
