cgcreate: fix the wrong uid/gid set.

cgcreate: fix the wrong uid/gid set.

When setting the cgconfig.conf as follow:

mount {
	memory = /cgroup/memory;
}

group . {
	perm {
		task {
			gid = w00227741;
			uid = w00227741;
			fperm =755;
		}
		admin {
			gid = w00227741;
			uid = w00227741;
			fperm =755;
			dperm = 755;
		}
	}
	memory {
	}
}

and restart the cgconfig service. Then switch to the user w00227741
and cgcreate cgroup like this:

# lscgroup
memory:/

# cgcreate -g memory:test
cgcreate: can't create cgroup test: Operation not permitted

the command report the error, but the cgroup test has created:

# lscgroup
memory:/
memory:/test

this patch fix the problem.
