KVM: ignore reads from AMDs C1E enabled MSR
commit 1fdbd48c242db996107f72ae4140ffe8163e26a8 upstream.
If the Linux kernel detects an C1E capable AMD processor (K8 RevF and
higher), it will access a certain MSR on every attempt to go to halt.
Explicitly handle this read and return 0 to let KVM run a Linux guest
with the native AMD host CPU propagated to the guest.
