[PATCH v2 07/29] ACPI: video: Remove acpi_video_bus from list before tearing it down

[Hans de Goede]

Move the list_del removing an acpi_video_bus from video_bus_head
on teardown to before the teardown is done, to avoid code iterating
over the video_bus_head list seeing acpi_video_bus objects on there
which are (partly) torn down already.
