Fix missed ReleaseVariableStats() in intarray's _int_matchsel().

Given a WHERE clause like "int[] @@ query_int" or "query_int ~~ int[]"
where the query_int side is a table column having statistics,
_int_matchsel() exited without remembering to free the statistics
tuple. This would typically lead to warnings about cache refcount
leakage, like
WARNING: resource was not closed: cache pg_statistic (73), tuple 42/12 has count 1
It's been wrong since this code was added, in commit c6fbe6d6f.
