perf annotate-data: Ensure the number of type histograms
Arnaldo reported that there is a case where nr_histograms and histograms
don't agree each other.
It ended up in a segfault trying to access a NULL histograms array.
Let's make sure to update the nr_histograms when the histograms array is
changed.
