core: pad: call tracer query-post hook after probes

Browse source 
Tracers are likely interested about the end result of the query, so
after probes have been caled.

Fix a bug where the buffer-lateness tracer was reporting a wrong latency
when pad probes increased the latency.

Also call the tracer hook if the pad has no query function.
