Dan Schatzberg 9308f9c9c7 cgroup: Fix rootcg cpu.stat guest double counting ...

[ Upstream commit 81c49d39aea8a10e6d05d3aa1cb65ceb721e19b0 ]

In account_guest_time in kernel/sched/cputime.c guest time is
attributed to both CPUTIME_NICE and CPUTIME_USER in addition to
CPUTIME_GUEST_NICE and CPUTIME_GUEST respectively. Therefore, adding
both to calculate usage results in double counting any guest time at
the rootcg.
