Good catch, the logic here is incorrect if attrib is not a service
declaration. I think this method should basically return the end
handle of the group the attribute belongs to. I don't know if this is
what Luiz originally intended but since the only two legitimate
attribute group types allowed by GATT are primary and secondary
service declarations, I take the end handle here to mean the
corresponding service end handle.
