Arnaldo Carvalho de Melo fec9cbd15b perf hists: Print number of samples, not the period sum
So that we match the header where we state the number of events with the
"Samples" column when using 'perf report -n/--show-nr-samples':

 [root@emilia ~]# perf record -a sleep 1
 [ perf record: Woken up 1 times to write data ]
 [ perf record: Captured and wrote 0.111 MB perf.data (~4860 samples) ]
 [root@emilia ~]# perf report --stdio --show-nr-samples
 # Events: 11  cycles
 #
 # Overhead  Samples        Command       Shared Object                        Symbol
 # ........ ..........  ...........  ..................  ............................
