The packet_trace() call is not ideal in format_packet() as we would print
a trace when a packet is formatted and (potentially) when the packet is
actually send. This was no problem up until now because format_packet()
was only used by one function. Fix it by moving the trace call into the
function that actually sends the packet.

It looks like there are two functions: packet_write() and
packet_buf_write().

I did not call trace in packet_buf_write() because this function does not
perform any writes.

Your patch only touches one of them, and it looks like we would fail to
trace many packets (e.g., see receive-pack.c:report(), which uses
packet_buf_write() and then write()s out the result).

I see. But isn't it confusing if packet_buf_write() issues a trace call?
If I just call this function then nothing happens at all. Shouldn't the
trace call be made in receive-pack.c:report() ? Or shouldn't receive-pack
let pkt-line.c perform the write calls?
