cpusets: fix bug when adding nonexistent cpu or mem
Adding a nonexistent cpu to a cpuset will be omitted quietly. It should return -EINVAL. Example: (real_nr_cpus <= 4 < NR_CPUS or cpu#4 was just offline) # cat cpus 0-1 # /bin/echo 4 > cpus # /bin/echo $? 0 # cat cpus # The same occurs when add a nonexistent mem. This patch will fix this bug. And when *buf == "", the check is unneeded.
