hexdump: remove the trailing space

For example:
        hex_dump_to_buffer("AB", 2, 16, 1, buf, 100, 0);
        pr_info("[%s]\n", buf);

I'd expect the output to be "[41 42]", but actually it's "[41 42 ]"

This patch also makes the required buf to be minimum.  To print the hex
format of "AB", a buf with size 6 should be sufficient, but
hex_dump_to_buffer() required at least 8.
