KVM: x86: emulating RDPID failure shall return #UD rather than #GP
[ Upstream commit a9e2e0ae686094571378c72d8146b5a1a92d0652 ]
Per Intel's SDM, RDPID takes a #UD if it is unsupported, which is more or
less what KVM is emulating when MSR_TSC_AUX is not available. In fact,
there are no scenarios in which RDPID is supposed to #GP.
