Don't send "cannot connect" errors on invalid startup packet

Browse Source 
Commit 16671ba6e7 moved the code that sends "sorry, too many clients
already" and other such messages, but it had the effect that we would
send that error even if the the startup packet processing failed, e.g.
because the client sent an invalid startup packet. That was not
intentional.

Spotted while reading the code again.
