Log Message:
Fix usb_rem_task_wait API.

- Return whether it removed task from queue or not.
  . True if it was on the queue and we intercepted it before it ran.
  . False if we could not intercept it: either it wasn't queued,
    or it already ran.  (Up to caller to distinguish these cases.)
- Pass an optional interlock like callout_halt.

While here, simplify.
