[PATCH ocserv 1/3] Add default case for 'restrict-user-to-ports' switch

[cernekee at gmail.com (Kevin Cernekee)]

This fixes a compiler warning:

      CC       main-user.o
    main-user.c: In function ?call_script?:
    main-user.c:215:7: warning: ?ret? may be used uninitialized in this function [-Wmaybe-uninitialized]
        if (ret < 0) {
           ^
    main-user.c:66:6: note: ?ret? was declared here
      int ret;
          ^

It's not really necessary because proto gets checked when the option is
parsed, but gcc doesn't know that.
