Fix up trivial conflicts due to the same cgroup API thinko fix going
through both Andrew and the networking tree.  However, there were small
differences between the two, with Andrew's version generally being the
nicer one, and the one I merged first. So pick that one.

Conflicts in: include/linux/cgroup.h and kernel/cgroup.c
