iwlwifi: convert hex_dump_to_buffer() to %*ph
There is no need to use hex_dump_to_buffer() in the cases like this:
hexdump_to_buffer(buf, len, 16, 1, outbuf, outlen, false); /* len <= 16 */
sprintf("%s\n", outbuf);
since it maybe easily converted to simple:
sprintf("%*ph\n", len, buf);
Note: it seems in one case the output is groupped by 2 bytes and looks like a
typo. Thus, patch changes that to plain byte stream.
