BandwidthController: reject with port-unreachable to prevent TCP retries.

Currently the bandwidth controller will cut off traffic via an ICMP
destination unreachable message with code "administratively prohibited".
TCP's RFC1122 does not explicitly say what to do with it, but it does say
to abort the transmission when "port-unreachable" is seen.

Some servers keep on retrying with the "prohibited" ICMP message which
keeps the radio longer awake as more packets come in.
