MINOR: connection: adjust CO_FL_NOTIFY_DATA after removal of flags

After the removal of CO_FL_DATA_RD_SH and CO_FL_DATA_WR_SH, the
aggregate mask CO_FL_NOTIFY_DATA was not updated. It happens that
now CO_FL_NOTIFY_DATA and CO_FL_NOTIFY_DONE are similar, which may
reveal some overlap between the ->wake and ->xprt_done callbacks.
We'll see after the mux changes if both are still required.
