MT#55283 reset read events after loop cap

Partial backport of 6a8c523d5

If we hit the maximul allowed loop iterations when reading packets and
end up aborting the loop, we must set active_read_events back to zero,
so that the next time a read event is received we actually do the
processing instead of thinking there's still an active thread.
