sw64: fix the error of cpufreq update 

Sunway inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IB73UR



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

When adjusting the cpu frequency, if 0 is returned, it is a correct
execution return. if a non-zero value is returned, it is an incorrect
execution return. the current logic is wrong and has been fixed.
