rx: Don't limit the # of packets sent in recovery
The RX transmit engine limits the number of packets sent whilst in
loss recovery to one per invocation of the transmit engine. As the
engine cannot be called by the application thread whilst in recovery,
this means that we end up being limited to one packet per ACK received,
which means that despite a growing congestion window we'll only send
one packet per RTT (in effect, a congenstion window of 1).
This will remain the case until we exit recovery, and all of a sudden
can send a large number of packets. If this is larger than the current
capacity of the network, we'll probably end straight back in recovery
again.
Let the congestion window do its job, by removing this arbitrary limit.
