[PATCH] cpufreq: amd_freq_sensitivity: Fix sensitivity clamping in amd_powersave_bias_target

[Thorsten Blum]

The local variable 'sensitivity' was never clamped to 0 or
POWERSAVE_BIAS_MAX because the return value of clamp() was not used. Fix
this by assigning the clamped value back to 'sensitivity'.
