perf annotate-data: Show the sample count in the data-type browser

Browse Source 
The data-type browser has a samples view, selected with -n (or with
annotate.show_nr_samples), in which browser__write_overhead() prints a
local nr_samples variable that is initialized to zero and never
updated, so every member is listed as having no samples while the
period and percent columns for the same entry are filled in.

Print the histogram entry's own count instead.

This predates the load/store counter split, so fix it ahead of that
patch: the split then only has to adapt a line that is already correct,
and this fix can be picked on its own.
