perf symbols: dso->name is an array, no need to check it against NULL
As it will always evaluate to 'true', as reported by clang:
util/map.c:390:36: error: address of array 'map->dso->name' will always
evaluate to 'true' [-Werror,-Wpointer-bool-conversion]
if (map && map->dso && (map->dso->name || map->dso->long_name)) {
~~~~~~~~~~^~~~ ~~
util/map.c:393:22: error: address of array 'map->dso->name' will always
evaluate to 'true' [-Werror,-Wpointer-bool-conversion]
else if (map->dso->name)
~~ ~~~~~~~~~~^~~~
