cgroup: fix sparse warning of shadow symbol in cgroup.c
cgroup: fix sparse warning of shadow symbol in cgroup.c

Fix a code warning: symbol 'p' shadows an earlier one

This is a reincarnation of Harvey Harrison's patch:
	cpuset: sparse warnings in cpuset.c

Independently, Cliff Wickman moved the affected code,
from kernel/cpuset.c to kernel/cgroup.c, in his patch:
	cpusets: update_cpumask revision
