perf symbols: only set vmlinux longname & mark loaded if really loaded
dso__load_vmlinux() uses the filename passed to it to directly set the
dso long_name, which resulted in a use after free due to
dso__load_vmlinux_path() treating 0 symbols as a load failure and
subsequently freeing the contents of dso->long_name.
Change dso__load_vmlinux() so that finding 0 symbols does not cause it
to consider itself loaded, and do not set long_name in such a case.
