Peter Boonstoppel 4166fc2f87 gpu: nvgpu: Fix null ptr in gm20b_tegra_postscale() ...

If devfreq governor is called from a timer during boot it is
possible that gm20b_tegra_postscale() gets called before we have
called gk20a_tegra_scale_init(). This change adds an explicit null ptr
check to prevent any null ptr dereference.
