cpufreq: interactive: don't skip waking up speedchange_task if target_freq > policy->cur
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.
