In the current setting, clock arbiter skips setting the clock if its already set previously. The value set by the arbiter is stored in "struct nvgpu_clk_arb->actual" whenever the clock is updated via the arbiter. However, DVFS might also update the clock and the updates are not synchronized with the arbiter. Hence, ensure that any clock requests are always updated i.e. the requested rate is set even if the previous rate remains the same.
