bgpd/security: CVE-2010-1674 Fix crash due to extended-community parser error
* bgp_attr.c: (bgp_attr_ext_communities) Certain extended-community attrs can leave attr->flag indicating ext-community is present, even though no extended-community object has been attached to the attr structure. Thus a null-pointer dereference can occur later. (bgp_attr_community) No bug fixed here, but tidy up flow so it has same form as previous. Problem and fix thanks to anonymous reporter.
