[libvirt PATCH 1/4] remote: Propagate error from virDomainGetSecurityLabelList via RPC
The daemon side of this API has been broken ever since the API was
introduced in 2012. Instead of sending the error from
virDomainGetSecurityLabelList via RPC so that the client can see it, the
dispatcher would just send a successful reply with return value set to
-1 (and an empty array of labels). The client side would propagate this
return value so the client can see the API failed, but the original
error would be lost.
