rxrpc: Only set DF=1 on initial DATA transmission
Change how the DF flag is managed on DATA transmissions. Set it on initial
transmission and don't set it on retransmissions. Then remove the handling
for EMSGSIZE in rxrpc_send_data_packet() and just pretend it didn't happen,
leaving it to the retransmission path to retry.
The path-MTU discovery using PING ACKs is then used to probe for the
maximum DATA size - though notification by ICMP will be used if one is
received.
