[LINUX] Do not early-unpin pagetables that contain foreign mappings.
This fixes a bug whereby foreign pages were freed by the unpin, which
then become owned by the local domain before it destroys its ptes.
It therefore (erroneously) detects the mappings as local and so
updates reference counts, leading to crashes.
