cpufreq: governors: Remove duplicate check of target freq in supported range

cpufreq: governors: Remove duplicate check of target freq in supported range

Function __cpufreq_driver_target() checks if target_freq is within
policy->min and policy->max range. generic_powersave_bias_target() also
checks if target_freq is valid via a cpufreq_frequency_table_target()
call. So, drop the unnecessary duplicate check in *_check_cpu().
