KVM: x86: Wrong assertion on paging_tmpl.h

Even after the recent fix, the assertion on paging_tmpl.h is triggered. Apparently, the assertion wants to check that the PAE is always set on long-mode, but does it in incorrect way. Note that the assertion is not enabled unless the code is debugged by defining MMU_DEBUG. Signed-off-by: Nadav Amit <[email protected]> Signed-off-by: Paolo Bonzini <[email protected]>
