server: Do not signal read/write bits if there are read/write asyncs waiting.

This is validated by tests introduced in
59beffb46c813a3de2eae6f28e3f7f321f666e89 etc. This commit alone doesn't fix said
tests, because:

* on this poll, we will alert the waiting async;

* when reselecting, we will still request POLLIN, because the AFD_POLL_READ
  request is still active,

* when POLLIN is subsequently signaled, we do not remove it in
  sock_dispatch_asyncs(), because we check async_waiting(), not async_queued().
