qemu_clock_run_timers() only takes care of main_loop_tlg, we shouldn't
forget aio timer list groups.
Currently, the qemu_clock_deadline_ns_all (a few lines above) counts all
the timergroups of this clock type, including aio tlg, but we don't fire
them, so they are never cleared, which makes a dead loop.
For example, this function hangs when trying to drive throttled block
request queue with qtest clock_step.
