From: Arnaldo Carvalho de Melo <a...@redhat.com>
In dc323ce8e72d ("perf script: Enable printing of branch stack") it
first tries to find the map for an address, then the symbol in the DSO
backing that map, for that address, well, this is what
thread__find_symbol() does, so just use it and make the code shorter.
