x86/mm: remove 'p2m_guest' lookup type.
It was neither consistently used by callers nor correctly handled by the
lookup code. Instead, treat any lookup that might allocate or unshare
memory as a 'guest' lookup for the purposes of:
- detecting the highest pod gfn populated; and
- crashing the guest on access to a broken page
which were the only things this was used for.
