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.
