[X][SRU][PATCH 1/1] selftests/cpu-hotplug: exit with failure when test occured unexpected behaviors

[Po-Hsu Lin]

From: Li Zhijian <lizhijian at cn.fujitsu.com>

BugLink: https://bugs.launchpad.net/bugs/1809699

Previously, 'make run_tests -C cpu-hotplug' always PASS since cpu-on-off-test.sh
always exits 0 even though the test got some unexpected errors like below:
root at debian9:/home/lizhijian/chroot/linux/tools/testing/selftests/cpu-hotplug# make run_tests
pid 878's current affinity mask: 1
pid 878's new affinity mask: 1
CPU online/offline summary:
Cpus in online state: 0
        Cpus in offline state: 0
Limited scope test: one hotplug cpu
        (leaves cpu in the original state):
        online to offline to online: cpu 0
./cpu-on-off-test.sh: line 83: /sys/devices/system/cpu/cpu0/online: Permission denied
offline_cpu_expect_success 0: unexpected fail
./cpu-on-off-test.sh: line 78: /sys/devices/system/cpu/cpu0/online: Permission denied
online_cpu_expect_success 0: unexpected fail
selftests: cpu-on-off-test.sh [PASS]

after this patch, the test will exit with failure once it occurs some unexpected behaviors
