Fix two bugs that cause x86 PV guest crashes.

Browse source 
1. Ballooning a 32-bit guest would eventually crash it.
 
 2. Revert a broken fix for a regression with NUMA_BALACING.  The bad
    fix caused PV guests to crash after migration.  This is not ideal
    but unpicking the madness that is _PAGE_NUMA == _PAGE_PROTNONE will
    take a while longer.
