mailinfo: recycle strbuf in check_header()

handle_message_id() duplicates the contents of the strbuf that is passed to it. Its only caller proceeds to release the strbuf immediately after that. Reuse it instead and make that change of object ownership more obvious by inlining this short function. Signed-off-by: Rene Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
