Chunyu Hu 1177eca042 cpufreq: cppc_cpufreq: Fix cppc_cpufreq_init() failure path 
[ Upstream commit 55b55abc17 ]

Kmemleak reported the below leak. When cppc_cpufreq_init went into
failure path, the cpu mask is not freed. After fix, this report is
gone. And to avaoid potential NULL pointer reference, check the cpu
value first.

unreferenced object 0xffff800fd5ea4880 (size 128):
