Matthew Auld 892bfb8a60 drm/i915/fbdev: fixup setting screen_size
Since we are actually mapping the object and not the vma, when dealing
with LMEM, we should be careful and use the backing store size here,
since the vma->node.size could have all kinds of funny padding
constraints, which could result in us writing to OOB address.

v2(Chris):
  - Prefer vma->size here, which should be the backing store size. Some
    more rework is needed here to stop using node.size in some other
    places.
