Alex Waterman 9b7b5c3aff gpu: nvgpu: Fix ordering of wmb() in gk20a_writel() ...

Putting the wmb() before the write only ensures that any previous
writes are done. But this doesn't really do anything for the
writel_relaxed(). The point of the wmb() here is to ensure that
the write performed by the writel_relaxed() is actually done
before proceeding.
