backend: ensure that we run verification for short time based jobs

We need to break out of the main loop for the case where we did
exceed our bytes issued, if we have verification to run. For
time based jobs, we'll get back in this loop after verification.

Fixes c04e4661e4da ("time_based: Avoid restarting main I/O loop")
