[PATCH] perf data convert json: Fix addr_location leak on time-filtered samples

[Tanushree Shah]

When samples are skipped due to time filtering in process_sample_event(),
the early return path bypasses addr_location__exit(), causing memory leaks
of thread, map, and maps references acquired by machine__resolve().

These references must be released through addr_location__exit() before
returning.

Fixes: 8e746e95c3e4 ("perf data: Allow filtering conversion by time range")
