Subject: [PATCH 4/4] perf annotate: Get rid of symbol__ensure_annotate()

Now symbol__annotate() is reentrant and it doesn't need to remove
non-instruction lines.  Let's get rid of symbol__ensure_annotate() and
call symbol__annotate() directly.  Also we can use it to get the arch
pointer instead of calling evsel__get_arch() directly.
