bgpd: use bgp_attr_malformed()

Some of the recent attribute flags/length checks copied from QRE use
bgp_notify_send_with_data() directly, but master branch assumes
using bgp_attr_malformed().

* bgp_attr.c
  * bgp_attr_med()
  * bgp_attr_local_pref()
  * bgp_attr_atomic()
  * bgp_attr_originator_id()
  * bgp_attr_cluster_list()
  * bgp_mp_reach_parse()
  * bgp_mp_unreach_parse()
