This allows user-space to properly deallocate fbs and dumb buffers
before closing the device.
This drops the "unplugged" flag hack, which puts the device in a
non-functional state after USB unplug and rejects most operations on
the device such as ioctls with error -ENODEV.

When USB cable is disconnected, we mark udl device as unplugged so that
udl_detect reports connector status as disconnected, but still keep
the drm device alive until user-space closes it.

But drm_release() does return a retcode. It would still make sense to
return that as-is in case any existing code relies on it.

proposed adding an "UNPLUG_DISALLOW" flag to ioctls so that we
can whitelist them on a case-by-case basis but that proposal got shot down

Remove the general drm_device_is_unplugged() checks, and move the unplugged
