In near future we will want to check whether capabilities for
given virtType exist, but report an error on our own. Introduce
reportError argument which makes the function report an error iff
set.
In one specific case (virQEMUCapsGetDefaultVersion()) we were
even overwriting (more specific) error message reportd by
virCapabilitiesDomainDataLookup(). Drop that too.
