Subject: [zebra 19263] Another memory leak!! is zebra OSPF

   This memory leak gets into picture whenever any interface goes down.

 Problem found and desctription: Whenever the interface goes down, the
 "def_params" (member of ospf_if_info) structure memory is not freed.

 Fix made: added the following line to free the "def_params" memory of
 ospf_if_info before calling the  "XFREE(MTYPE_OSPF_IF_INFO, ifp->info);"
 The added line is:
       ospf_del_if_params ((struct ospf_if_params *) IF_DEF_PARAMS (ifp));
