drm/i915: Fix transposed arguments to skl_plane_wm_level() 

Accidentally transposed the arguments to skl_plane_wm_level()
which is causing us to mistakenly think that the plane watermarks
have/have not changed when the opposite may be true. Swap the
arguments so this actually works.

The other uses of this look OK.
