KVM: x86: disable paravirt mmu reporting
commit a68a6a7282373bedba8a2ed751b6384edb983a64 upstream
Disable paravirt MMU capability reporting, so that new (or rebooted)
guests switch to native operation.
Paravirt MMU is a burden to maintain and does not bring significant
advantages compared to shadow anymore.
