usb: wusbcore: fix stranded URB after HWA unplug

Browse source

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.
