ASoC: Tegra: Don't return mclk_changed from utils_set_rate

Browse Source 
Only the clock programming code needs to know whether the clocks changed,
and that is encapsulated within tegra_asoc_utils_set_rate(). The machine
driver's call to snd_soc_dai_set_sysclk(codec_dai, ...) is safe
irrespective of whether the clocks changed.

(Applying Mark's TrimSlice review comments to the existing driver)
