When processing an SADB_DELETE message, allow SADB_EXT_SA to be blank.  In this case, we delete all non-LARVAL SAs that match the src/dst/protocol.  This is particularly useful in IKE INITIAL-CONTACT processing.  Idea from Bill Sommerfeld <sommerfeld@east.sun.com>, who implemented it in post-Solaris8.
