KVM: x86: Mark x2APIC DFR reg as non-existent for x2APIC
Mark APIC_DFR as being invalid/non-existent in x2APIC mode instead of
handling it as a one-off check in kvm_x2apic_msr_read(). This will allow
reusing "valid_reg_mask" to generate VMX's interception bitmaps for
x2APIC. Handling DFR in the common read path may also fix the Hyper-V
PV MSR interface, if that can coexist with x2APIC.
