sw64: fix cpu reduction bug in cpuautoplug 

Sunway inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IBDJNZ



--------------------------------

This patch fixs a critical bug in cpuautoplug subsystem related to
cpufreq subsystem. With performance policy, the number of active
cpus may be reduced to the minimum count because global variable
curruent_policy is uninitialized.
