rxrpc: Don't let ack.previousPacket regress
The previousPacket field in the rx ACK packet should never go backwards -
it's now the highest DATA sequence number received, not the last on
received (it used to be used for out of sequence detection).
Fixes: 248f219cb8bc ("rxrpc: Rewrite the data and ack handling code")
