Subject: [PATCH] video: don't use flush_scheduled_work() in fb_defio

flush_scheduled_work() in on the way out.  fb_deferred_io_cleanup()
can simply sync-cancel info->deferred_work instead of cancel +
flush_scheduled_work().  Drop flush_scheduled_work() usage.

Compile tested.  I'm planning on marking flush_scheduled_work()
deprecated in linux-next so it would be great if this can show up
there soonish.  Thank you.
