        src/sys/external/bsd/common/include/linux: workqueue.h
        src/sys/external/bsd/common/linux: linux_work.c

Log Message:
Fix semantics of flush_work and flush_delayed_work.

- Change return type to void.
  => Upstream it is bool, but exactly one of hundreds of callers
     actually use it, and I don't think the semantics is clear.

- Make sure to wait for whichever of the current work _and_ the next
  batch queued is currently there in the workqueue.

- Don't retry a cancelled callout.  Cancellation in the state
  DELAYED_WORK_CANCELLED is guaranteed.
