This fixes a bug in changeset 22526:7a5ee3800417, where the wrong
value is read when deciding whether to flush the VTd tables. The
effect is minor: in situations where the p2m entry is changed but the
mfn is the same, the VTd tables will be unnecessarily flushed.
old_entry is left untouched in the second case, since having a present
old_entry will cause the an unnecessary check to be taken at the end
of the function.
