When __cpufreq_driver_target() in speedchange_task failed for some reason, the policy->cur could be lower than the target_freq. The governor misses to change the target_freq if the target_freq is equal to the next_freq at the next sample time. Added a check to prevent the CPU to stay at the speed that is lower than the target_freq for long duration.
