[PATCH 3/6] libsemanage: silence -Wextra-semi-stmt warning

[Nicolas Iooss <nicolas.iooss@xxxxxxx>]

On Ubuntu 20.04, when building with clang -Werror -Wextra-semi-stmt
(which is not the default build configuration), the compiler reports:

      genhomedircon.c:742:67: error: empty expression statement has no
      effect; remove unnecessary ';' to silence this warning
      [-Werror,-Wextra-semi-stmt]
              const semanage_seuser_t **u2 = (const semanage_seuser_t **) arg2;;
                                                                               ^
