g_dev_orphan(): Return early if the device is already gone
The following panic was the result of running "cdcontrol eject"
after using the physical ejection key on the device before the
tray was actually ejected.
The device was loaded with a DVD.

The system was based on 11-STABLE r310319 with ElectroBSD
patches that shouldn't be relevant.
I didn't notice any recent commits that seem relevant and assume
the issue can occur on other branches as well.
For now I'm using the attached patch to let g_dev_orphan()
return early if the device is already gone.
A more elegant solution could be to prevent geom from trying
to orphan the device when it's already gone but I haven't
looked into this yet.
