Deepak Nibade 625f652f89 devfreq: set current freq in case no change required ...

API scaling_state_check() returns 0 in case no change
in frequency is required
In nvhost_pod_estimate_freq(), we set *freq to 0
in case scaling_state_check() returns 0

And as a result of this, update_devfreq() will just
keep setting minimum frequency instead of keeping
same frequency - and this results in huge
performance degradation

To fix this, set *freq to current frequency in case
scaling_state_check() returns 0 as estimated
frequency
