OPTIM: sink: don't waste time calling sink_announce_dropped() if busy

If we see that another thread is already busy trying to announce the
dropped counter, there's no point going there, so let's just skip all
that operation from sink_write() and avoid disturbing the other thread.
This results in a boost from 244 to 262k req/s.
