Subject: [PATCH] Update ngx_http_v3_parse.c

Apologies for the confusion. I had initially pasted the code incorrectly, which caused an empty or malformed diff.
This updated commit adds a log message when Huffman decoding fails, to help catch malformed field lines associated with CVE-2024-24989. It does not change spacing or logic beyond that.
