Simplify client's buffer overflow HEAD master

So I decided to kill a link when there's no IRC message within 512
bytes, because doing so removes code and IMO makes it more clear

If peer->recvd == sizeof(peer->buf), then buffer size passed into next
read(peer->fd) will be 0, therefore its return value will be 0. Though,
this means that link is almost dropped if it sent exactly 512 bytes not
containing an \r\n: they can get information, but on next send ircd
will close the connection. But this state is unachievable with an IRC
client: it either sends a message <= 512 bytes containing an \r\n, or,
if one or more bytes longer, well that's already > 512 bytes hence link
is still ready to be read and will be kicked after the next poll()
