mod_smacks: Send out more ack requests where needed
Under some circumstances it was possible that more than "max_unacked_stanzas"
where left in the outgoing stanza queue without forcing an ack.
This could happen, when more stanzas entered the queue while the last ack request
was still unanswered.
Now the test "#queue > max_unacked_stanzas" is done upon receiving
an ack as well as when sending out stanzas, which fixes this bug.
