mptcp: remove unused data_ack from struct mptcp_ext
The data_ack and data_ack32 fields in struct mptcp_ext are no longer used
anywhere. Remove them from the structure and update mptcp_dump_mpext()
trace helper accordingly. Drop the data_ack field from the trace entry
and the corresponding output in TP_printk().
