can: j1939: j1939_tp_rxtimer(): fix errant alert in j1939_tp_rxtimer

When the session state is J1939_SESSION_DONE, j1939_tp_rxtimer() will
give an alert "rx timeout, send abort", but do nothing actually. Move
the alert into session active judgment condition, it is more
reasonable.

One of the scenarios is that j1939_tp_rxtimer() execute followed by
j1939_xtp_rx_abort_one(). After j1939_xtp_rx_abort_one(), the session
state is J1939_SESSION_DONE, then j1939_tp_rxtimer() give an alert.
