perf annotate: Add the cmp_null function and make use of it

Browse source

This function exists in builtin-report.c but not in
builtin-annotate.c Functions that use cmp_null are shorter and
clearer.

Synchronizing functions between these two files will also make it
easier to potential share code in the future.
