PM / devfreq: tegra: Set freq in rate callback

As per the documentation of the devfreq_dev_profile.target callback, set
the freq argument to the new frequency before returning.

This caused endless messages like this after recent changes in the core:

devfreq 6000c800.actmon: Couldn't update frequency transition information.
