This was added mainly for help in debugging, if debug is not enabled. Sometimes we get logs
where it's hard to tell what happened to particular session. Moreover session deletion is not
very common scenario.

In that case, I would also prefer to see message coming out from qlt_schedule_sess_for_deletion(), because that’s where you can track that session is scheduled for deletion. 

I would prefer this message also changed to ql_log_warn. 

        ql_dbg(ql_dbg_disc, sess->vha, 0xe001,
            "Scheduling sess %p for deletion %8phC\n",
            sess, sess->port_name);
