perf script: Fix callchain addresses in db-export
Remove the call to map_ip() to adjust al.addr, because it has already been called when assembling the callchain, in: thread__resolve_callchain_sample(perf_sample) add_callchain_ip(ip = perf_sample->callchain->ips[j]) thread__find_addr_location(addr = ip) thread__find_addr_map(addr) { al->addr = addr if (al->map) al->addr = al->map->map_ip(al->map, al->addr); } Calling it a second time can result in incorrect addresses being used. This can have effects such as duplicate symbols being created and exported.
