greybus: hd: fix host-device-removal race

Browse source

Make sure to tear down the svc and flush any on-going hotplug processing
before removing the remaining interfaces.

This fixes crashes due to host-device removal racing with svc
hotplug/unplug processing (e.g. at "UniPro restart").

Testing Done:
Verified that this fixes crashes reproducible on SDB when unloading the
host-device driver module while generating hotplug/unplug events.
