drm/i915: Use adjusted_mode appropriately when computing watermarks
I guess we should renable the enabled local variable into something a
notch more descriptive, but that's something for -next.
The effect on my i945gme netbook is pretty severe amounts of underruns
- usually the very first pixel gets used for the entire screeen.
