drm/i915: Move the NULL sg handling out from rotate_pages()
rotate_pages() checks to see if it got called with a NULL sg, and then
goes to extract it from sg->sgl. It always gets called with a NULL sg
for the first plane, so moving the initial 'sg=st->sgl' assignment out
into intel_rotate_fb_obj_pages() seems less special-casey.
