configure.ac: fix protobuf config

Browse source 
Bug description: frr_init load zebra_fpm.so error. Zebra can't
  find function `zfpm_protobuf_encode_route` in symbol table.

  Bug trigger condition ( CI have this set ):
    ./configure --enable-protobuf=no --enable-fpm=yes
    /usr/lib/frr/zebra -M fpm

  Cause: Macro `HAVE_PROTOBUF` and compile condition variable
  `HAVE_PROTOBUF`  in `configure.ac ` is not consistent. When
  configure `disable-protobuf`, compile condition variable
  `HAVE_PROTOBUF` is 0, but the macro is 1. It leads to zebra
  load protobuf module, but protobuf module is not linked.

  Fix: add a same condition statement to the macro define.
