fpsdisplaysink: initialize interval_ts and last_frames_* counters

Initialize interval_ts to first QOS event timestamp, otherwise the
fps statistics are printed always after one rendered frame.
Also, initialize last_frames_* counters, the values are bogus e.g. after
PLAYING-NULL-PLAYING state change.
