KVM: VMX: Use precomputed MAXPHYADDR for RTIT base MSR check
Use cpuid_maxphyaddr() instead of cpuid_query_maxphyaddr() for the RTIT base MSR check. There is no reason to recompute MAXPHYADDR as the precomputed version is synchronized with CPUID updates, and MSR_IA32_RTIT_OUTPUT_BASE is not written between stuffing CPUID and refreshing vcpu->arch.maxphyaddr.
