[PATCH 04/15] perf hists: Convert hist entry functions to use struct he_stat

[Namhyung Kim <namhyung@kernel.org>]

From: Namhyung Kim <namhyung.kim@lge.com>

hist_entry__add_cpumode_period() and hist_entry__decay() are dealing
with hist_entry's stat fields only.  So make them use the struct
directly.
