Ken Chen a7a001eb00 latencytop: fix per task accumulator ...

commit 38715258aa upstream.

Per task latencytop accumulator prematurely terminates due to erroneous
placement of latency_record_count.  It should be incremented whenever a
new record is allocated instead of increment on every latencytop event.

Also fix search iterator to only search known record events instead of
blindly searching all pre-allocated space.
