pkt-line: move a misplaced comment

The comment describing the packet writing interface was originally written above packet_write, but migrated to be above safe_write in f3a3214, probably because it is meant to generally describe the packet writing interface and not a single function. Let's move it into the header file, where users of the interface are more likely to see it. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
