target/i386: sev: fail query-sev-capabilities if QEMU cannot use SEV
In some cases, such as if the kvm-amd "sev" module parameter is set to 0, SEV will be unavailable but query-sev-capabilities will still return all the information. This tricks libvirt into erroneously reporting that SEV is available. Check the actual usability of the feature and return the appropriate error if QEMU cannot use KVM or KVM cannot use SEV.
