Muhammad Adeel b25ba45fcf cgroup: Remove steal time from usage_usec
[ Upstream commit db5fd3cf8bf41b84b577b8ad5234ea95f327c9be ]

The CPU usage time is the time when user, system or both are using the CPU.
Steal time is the time when CPU is waiting to be run by the Hypervisor. It
should not be added to the CPU usage time, hence removing it from the
usage_usec entry.

Fixes: 936f2a70f2077 ("cgroup: add cpu.stat file to root cgroup")
