perf report: Remove the time slices number limitation

Browse Source 
Previously it was only allowed to use at most 10 time slices in 'perf

This patch removes this limitation.
For example, following command line is OK (12 time slices)

perf report --stdio --time 1%/1,1%/2,1%/3,1%/4,1%/5,1%/6,1%/7,1%/8,1%/9,1%/10,1%/11,1%/12
