ALSA: ua101: fix crash when unplugging
commit 862a6244eb9f9f5123fe819454fcfcae0ee1f2f9 upstream.
If the device is unplugged while running, it is possible for a PCM
device to be closed after the disconnect callback has returned. This
means that kill_stream_urb() and disable_iso_interface() would try to
access already-invalid or freed USB data structures.
The function free_usb_related_resources() was intended to prevent this,
but forgot to clear the affected variables.
