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

[Namhyung Kim <namhyung@kernel.org>]

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")
