Deepak Nibade f7c5a179fe gpu: nvgpu: remove railgate lock from gm20b_tegra_postscale ...

In gm20b_tegra_postscale(), we use platform->railgate_lock to check if GPU is
railgated or not

But platform->railgate_lock was introduced only to prevent unrailgating in midst
of gk20a_do_idle() sequence
This lock is not the right way to check railgate status since it is still
possible to railgate GPU with this lock being held

Hence remove acquire/release of platform->railgate_lock from
gm20b_tegra_postscale()
