Dominique Martinet 03a85825ed copy_user_pte: base memobj copy on range & VR_PRIVATE ...

Some memobjs (e.g. devobj) will not be considered 'in memobj' by
page_is_in_memobj.
Instead of trying to play whack-a-mole with the non-fileobj memobjs,
base the copy check on range's memobj and VR_PRIVATE (do not copy
MAP_SHARED mappings, so the fault handler will do the right thing™
when required)
