usb: wusbcore: fix stranded URB after HWA unplug
This patch adds error checking to the abort request callback to forcibly
clean up the dequeued transfers if the abort request failed. The
wa_complete_remaining_xfer_segs was modified so that it could be used in
this situation as well. This fixes a stranded URB/PNP hang when the HWA
is unplugged while playing audio to a wireless audio device.
