drm/i915: Use intel_fb_gtt_offset() also for gen2/3 primary plane

Browse Source 
The code to determine the primary plane offset for gen2/3 looks
different than the code for gen4+, but in fact it's doing the same
thing. Let's make it uniform. Allows us to eliminate the 'obj' from
the list of local variables as well.
