Subject: [PATCH 4.14 034/156] cpupowerutils: bench - Fix cpu online check
4.14-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 53d1cd6b125fb9d69303516a1179ebc3b72f797a ]
cpupower_is_cpu_online was incorrectly checking for 0. This patch fixes
this by checking for 1 when the cpu is online.
