Now that ptep_establish has a definition in PAE i386 3-level paging code,
the only paging model which is insane enough to have multi-word hardware
PTEs which are not efficient to set atomically, we can remove the ghost
of set_pte_atomic from other architectures which falesly duplicated it,
and remove all knowledge of it from the generic pgtable code.
set_pte_atomic is now a private pte operator which is specific to i386
