workqueue: add 'flush_delayed_work()' to run and wait for delayed work

It basically turns a delayed work into an immediate work, and then waits
for it to finish, thus allowing you to force (and wait for) an immediate
flush of a delayed work.

We'll want to use this in the tty layer to clean up tty_flush_to_ldisc().

[ Fixed to use 'del_timer_sync()' as noted by Oleg ]
