Phonet: fix flawed "SYN/ACK" logic
* Do not fail if the peer supports more or less than 3 algorithms.
* Ignore unknown congestion control algorithms instead of failing.
* Simplify congestion algorithm negotiation (largest is best).
* Do not use a static buffer.
* Fix off-by-two read overflow.
* Avoid extra memory copy (in addition to skb_copy_bits()).
The previous code really made no sense.
