Daniel T. Lee 71135b77aa samples/bpf: replace meaningless counter with tracex4 ...

Currently, compiling samples/bpf with LLVM warns about the unused but
set variable with tracex4_user.

    ./samples/bpf/tracex4_user.c:54:14:
    warning: variable 'i' set but not used [-Wunused-but-set-variable]
        int map_fd, i, j = 0;
                    ^
                    1 warning generated.

This commit resolve this compiler warning by replacing the meaningless
counter.
