Avi Kivity reported 'perf annotate' failures with modules, the requested function was not annotated. If there are no modules currently loaded, or the last module scanned is not loaded, dso__load_modules() steps on the value from dso__load_vmlinux(), so we happily load the kallsyms symbols on top of what we've already loaded. Fix that such that the total count of symbols loaded is returned. Should module symbol load fail after parsing of vmlinux, is's a hard failure, so do not silently fall-back to kallsyms.
