drm: make sure page protections are updated after changing vm_flags
Some architectures compute ->vm_page_prot depending on ->vm_flags, so we
need to update the protections after adjusting the flags.
AFAIK this only affects running X under Xen; without this patch you get
lots of coloured blobs on the screen, or maybe a complete lockup. Or
anything really.
But that still depends on lots of out-of-tree stuff, so I don't think
there are any consequences for anyone else. But it is wrong in principle.
