mem: Separate waiting for the bus and waiting for a peer
This patch splits the retryList into a list of ports that are waiting for the bus itself to become available, and a map that tracks the ports where forwarding failed due to a peer not accepting the packet. Thus, when a retry reaches the bus, it can be sent to the appropriate port that initiated that transaction. As a consequence of this patch, only ports that are really ready to go will get a retry, thus reducing the amount of redundant failed attempts. This patch also makes it easier to reason about the order of servicing requests as the ports waiting for the bus are now clearly FIFO and much easier to change if desired.
