Jiri Olsa d755330c5e perf tools: Fix segfault in cumulative.callchain report 
When cumulative callchain mode is on, we could get samples with
with no actual hits. This breaks the assumption of the annotation
code, that each sample has annotation counts allocated and leads
to segfault.

Fixing this by additional checks for annotation stats.
