discoverer: Set 'processing = FALSE' when done discovering SYNC

This avoids a race where we would get new tag but we are already
prerolled and analyzing results.

It is the way it is supposed to be handled as stated in comment:
"If preroll is complete, drop these tags - the collected information is
possibly already being processed and adding more tags would be racy"
