perf dlfilter: Initialize addr_location before passing it to thread__find_symbol_fb()
As thread__find_symbol_fb() will end up calling thread__find_map() and
it in turn will call these on uninitialized memory:
maps__zput(al->maps);
map__zput(al->map);
thread__zput(al->thread);
Fixes: 0dd5041c9a0eaf8c ("perf addr_location: Add init/exit/copy functions")
