drm/i915: Cleanup fbdev fb setup

Browse Source 
We use a mix of 'intel_fb' vs. 'ifbdev->fb' in the same function.
Both should be pointing at the same thing. Make things less
confusing by just getting existing fb from 'ifbdev->fb' at the
start and then sticking with the local 'fb' (renamed from the
'intel_fb') until the very end.

v2: rebase
