In code we have frozen the cgroup to avoid the processes get an occasional "permission denied" error, while the systemd's application of device rules is done disruptively. When the processes in the container can not be frozen over 2 seconds (which defined in fs/freezer.go), we still update the cgroup which resulting the container get an occasional "permission denied" error in some cases. Return error directly without updating cgroup, when freeze fails. Fixes: opencontainers#3803 Signed-off-by: Zoe <hi@zoe.im>

This is a backport of #3804 to release-1.1 branch. Original description follows.
In code we have frozen the cgroup to avoid the processes get an occasional "permission denied" error, while the systemd's application of device rules is done disruptively. When the processes in the container can not be frozen over 2 seconds (which defined in fs/freezer.go), we still update the cgroup which resulting the container get an occasional "permission denied" error in some cases.
Return error directly without updating cgroup, when freeze fails.
