intel_wm_need_update() is a mess when it comes to variable
names and constness. The checks also keep alternating randomly
between 'old != cur' vs. 'cur != old'. Clean it all up.

Just noticed that the next patch in this series nuke this intel_wm_need_update() and move to
i9xx_wm_need_update(). So wonder if we need this patch.

Anyway, already RB-ed.

That's just a rename. Nothing to do with the internals of the function.
