Subject: [PATCH 17/41] perf machine: Remove machine__load_kallsyms()

From: Jiri Olsa <jolsa@...nel.org>

The current machine__load_kallsyms() function has no caller, so replace
it directly with __machine__load_kallsyms().  Also remove the no_kcore
argument as it was always called with a 'true' value.
