Subject: [PATCH 07/20] perf test: maps__merge_in: fix memory leak of maps

ASan reports a memory leak when running the perf test
"65: maps__merge_in". This is the second and final patch addressing
these memory leaks.
This time, the problem is simply that the maps object is never
destructed.

This patch adds the missing maps__exit call.
