Jiri Olsa dcabb507fd perf record: Store PERF_RECORD_FINISHED_ROUND only for nonempty rounds 
Currently we store PERF_RECORD_FINISHED_ROUND event each time
we go throught mmap buffers no matter if it contains any data,
which is useless.

Forcing the PERF_RECORD_FINISHED_ROUND event to be stored any
time we finished the round AND wrote at least one event.
