[XEN] Make the spurious page-fault detection logic
more robust. In particular it must be able to handle
spurious write faults on mappings that have been
changed from read-only to writable. If a CPU has a stale
read-only entry in its TLB, it is allowed to fault on
the next write access without re-walking the page table.
