drm/i915: fix i915 running as dom0 under Xen
Commit 920cf4194954ec ("drm/i915: Introduce an internal allocator for
disposable private objects") introduced a regression for the kernel
running as Xen dom0: when switching to graphics mode a GPU HANG
occurred.
Reason seems to be a missing adaption similar to that done in
commit 7453c549f5f648 ("swiotlb: Export swiotlb_max_segment to users")
to i915_gem_object_get_pages_internal().
So limit the maximum page order to be used according to the maximum
swiotlb segment size instead to the complete swiotlb size.
