[PATCH] test-sys_socket: avoid set-but-not-used warnings from gcc

[Jim Meyering]

One more.
Without the patch below, I'd get these:

    test-sys_socket.c:36:15: warning: variable 'i' set but not used 
[-Wunused-but-set-variable]
    test-sys_socket.c:35:27: warning: variable 'x' set but not used 
[-Wunused-but-set-variable]
