KVM: SVM: Do not virtualize MSR accesses for APIC LVTT register
AMD does not support APIC TSC-deadline timer mode. AVIC hardware
will generate GP fault when guest kernel writes 1 to bits [18]
of the APIC LVTT register (offset 0x32) to set the timer mode.
(Note: bit 18 is reserved on AMD system).
Therefore, always intercept and let KVM emulate the MSR accesses.
Fixes: f3d7c8aa6882 ("KVM: SVM: Fix x2APIC MSRs interception")
