can: j1939: transport: make sure the aborted session will be deactivated only once
j1939_session_cancel() was modifying session->state without protecting
it by locks and without checking actual state of the session.
This patch moves j1939_tp_set_rxtimeout() into j1939_session_cancel()
and adds the missing locking.
Fixes: 9d71dd0c7009 ("can: add support of SAE J1939 protocol")
