Subject: [PATCH] perf annotate-data: Check annotation on perf report TUI

As it removed the sample accounting for code when no symbol sort key is
given for perf report TUI, it might not allocate the annotated_source
yet.  Let's check if it's NULL first.

Fixes: 6cdd977ec24e1 ("perf report: Do not collect sample histogram unnecessarily")
