magumagu 36f01e141d Fix timing regression affecting ES_LAUNCH.
Scheduling an event for zero cycles in the future actually means zero
cycles with new timing changes, but the code for IPC ACKs was depending on
it meaning "soon".

Fixes #9511.

I'm not at all confident this is actually right... but it seems to work.
