Oliver Anderson 2eb64a2b4f hypervisor: Ensure required feature MSRs are successfully restored ...

Feature MSRs must have consistent values across snapshot and restore,
otherwise we risk subtle time of check to time of use errors.

We thus adapt `Vcpu::set_state` to return a hard error if any feature
MSR cannot be restored.

It is enough to check that each MSR failing to be set does not have
an address corresponding to any of the feature MSRs stored in the
`KvmVcpu`. This is because the `msrs` in the `VcpuKvmState` contain all
the feature MSRs required by the selected CPU profile by construction.
