Joel Fernandes e17731c2fd tracing: Treat recording comm for idle task as a success ...

commit eaf260ac04 upstream.

Currently we stop recording comm for non-idle tasks when switching from/to idle
task since we treat that as a record failure. Fix that by treat recording of
comm for idle task as a success.
