drm/xe: Set max pte size when skipping rebinds

When a rebind is skipped, we must set the max pte size of the newly
created vma to value of the old vma as we do not pte walk for the new
vma. Without this future rebinds may be incorrectly skipped due to the
wrong max pte size. Null binds are more likely to expose this bug as
larger ptes are more frequently used compared to normal bindings.
