KVM: X86: Fix MSR range of APIC registers in X2APIC mode
commit bf10bd0be53282183f374af23577b18b5fbf7801 upstream.
Only MSR address range 0x800 through 0x8ff is architecturally reserved
and dedicated for accessing APIC registers in x2APIC mode.
Fixes: 0105d1a52640 ("KVM: x2apic interface to lapic")
