Robert Hoo 8f6ecf9a3e KVM: x86: emulating RDPID failure shall return #UD rather than #GP ...

[ Upstream commit a9e2e0ae68 ]

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.
