[PATCH 03/11] target/i386/monitor: Return QMP error when SEV is disabled in build |

If the management layer tries to inject a secret, it gets an empty
response in case the binary built without SEV:
{ "execute": "sev-inject-launch-secret",
"arguments": { "packet-header": "mypkt", "secret": "mypass", "gpa":
4294959104 }
}
{
"return": {
}
}
Make it clearer by returning an error, mentioning the feature is
disabled:
{ "execute": "sev-inject-launch-secret",
"arguments": { "packet-header": "mypkt", "secret": "mypass", "gpa":
4294959104 }
}
{
"error": {
"class": "GenericError",
"desc": "this feature or command is not currently supported"
}
}
