[android-porting] cgroup failures

[Nagamani Cherukuri]

Hi All,

When I try to capture an image in AOSP 7.1.2 release, I observed
cgroup failure errors. I'm using kernel 4.16 version. I have seen the same
errors multiple times in logcat. I think the issue is with kernel 4.16. But
let me know how to fix this.
