cpuset: re-structure update_cpumask() a bit
Check if cpus_allowed is to be changed before calling validate_change().
This won't change any behavior, but later it will allow us to do this:
# mkdir /cpuset/child
# echo $$ > /cpuset/child/tasks /* empty cpuset */
# echo > /cpuset/child/cpuset.cpus /* do nothing, won't fail */
Without this patch, the last operation will fail.
