Subject: [PATCH v2 3/4] perf script: fix callchain addresses in db-export

Remove the call to map_ip, because it has already been called when
assembling the callchain. Calling it a second time can result in incorrect
addresses being used. This can have effects such as duplicate symbols
being created and exported.
