mod_smacks: fix bug for missbehaving clients sending multiple acks in a row
Missbehaving clients, sending multiple acks in a row (I'm looking at you Monal!)
triggered the ack-loop-prevention code added in 2017, leaving unacked stanzas
in the queue. This fixes the bug while still preventing ack-loops.
