[virt-tools-list] [libosinfo 2/4] loader: Set GError on osinfo_loader_nodeset failures

[Christophe Fergeau]

Most of the code in OsinfoLoader check if osinfo_loader_nodeset
set a GError to see if it failed and never test if it returned -1.
Better to make sure that we actually set the GError when this
function fails.
