zebra: tweak deletion of routes without nexthop addr

Browse Source 
* zebra/zserv.c

    - zread_ipv4_delete(): Pass a null 'gate' parameter to
      rib_delete_ipv4() if the route being deleted does not specify a
      next hop IP address. We were previously passing a pointer to a
      cleared out IP address.

    - zread_ipv4_add(): Fix indentation.
