MINOR: threads/queue: Get rid of THREAD_WANT_SYNC in the queue code.

Now that we can wake one thread sleeping in the poller, we don't have to
use THREAD_WANT_SYNC any more.

This gives a significant performance boost on highly contended accesses
(servers with maxconn 1), showing a jump from 21k to 31k conn/s on a
test involving 8 threads.
