KVM: x86/mmu: Only allocate shadowed translation cache for sp->role.level <= KVM_MAX_HUGEPAGE_LEVEL
Only the indirect SP with sp->role.level <= KVM_MAX_HUGEPAGE_LEVEL might
have leaf gptes, so allocation of shadowed translation cache is needed
only for it. Then, it can use sp->shadowed_translation to determine
whether to use the information in the shadowed translation cache or not.
Also, extend the WARN in FNAME(sync_spte)() to ensure that this won't
break shadow_mmu_get_sp_for_split().
