rxrpc: Add a reason indicator to the tx_data tracepoint
Add an indicator to the rxrpc_tx_data tracepoint to indicate what triggered
the transmission of a particular packet. At this point, it's only normal
transmission and retransmission, plus the tracepoint is also used to record
loss injection, but in a future patch, TLP-induced (re-)transmission will
also be a thing.
