media/video: don't use flush_scheduled_work()
This patch converts the remaining users of flush_scheduled_work() in
media/video.
* bttv-input.c and cx23885-input.c don't use workqueue at all. No
need to flush.
* Make omap24xxcam.c and saa7134-empress.c flush the used work
directly.
* In fd_defio.c, replace cancel_delayed_work() +
flush_scheduled_work() with cancel_delayed_work_sync(). While at
it, replace the deprecated cancel_rearming_delayed_work() with
cancel_delayed_work_sync().
