File openssl-0003-mime_hdr_addparam.patch of Package openssl-3

Description: Fix CWE-476 (NULL Pointer Dereference) in mime_hdr_addparam
Issue: The 'mhdr' pointer is dereferenced (mhdr->params) inside sk_MIME_PARAM_push, but static analysis indicates a path where 'mhdr' could be NULL when passed from mime_parse_hdr.
