KVM: x86: use guest maxphyaddr to check MTRR values
The check introduced in commit d7a2a246a1b5 (KVM: x86: #GP when attempts to write reserved bits of Variable Range MTRRs, 2014-08-19)
will break if the guest maxphyaddr is higher than the host's (which
sometimes happens depending on your hardware and how QEMU is
configured).
To fix this, use cpuid_maxphyaddr similar to how the APIC_BASE MSR
does already.
