Log Message:
Fix system freeze when USB NICs with multiple outstanding transfers
are detached from xhci(4) or ehci(4), that enable up_serialise for
bulk transfers.
The cause of problem is that usbd_ar_pipe() waits xfers of
USBD_NOT_STARTED to be removed, although underlying upm_abort
functions do not remove such queues, as reported by "sc dying".
Therefore, remove xfers of USBD_NOT_STARTED when pipe is closed.
