qla2xxx: Get rid of redundant qla_tgt_sess.tearing_down
The only place that sets qla_tgt_sess.tearing_down calls
target_splice_sess_cmd_list() immediately afterwards, without dropping
the lock it holds. That function sets se_session.sess_tearing_down,
so we can get rid of the qla_target-specific flag, and in the one
place that looks at the qla_tgt_sess.tearing_down flag just test
se_session.sess_tearing_down instead.
