[LTP] [PATCH 1/2] [PATCH] cpuset_hotplug: fix cpuset_list_compute

[Cristian Marussi]

cpuset_hotplug failed with:

Usage : cpuset_list_compute [-a|s] list1 [list2]

        -a|s   list1 add/subtract list2.[default: -a]

        -h     Help.
cpuset_hotplug 1 TFAIL: root group's cpus isn't expected(Result: 0,2-5, Expect: ).

It turned out that helper cpuset_list_compute was always failing because it was
improperly handling getopt retval.
