The session_index bug was in that patch, but I think it correctly kfreed
the session in __iscsi_target_login_thread.
I think it was this one that added the early kfree bug:
commit 0957627a99604f379d35831897a2aa15272528fc
Author: Nicholas Bellinger <nab@linux-iscsi.org>

iscsi-target: Fix sess allocation leak in iscsi_login_zero_tsih_s1
Dan's tools probably just did not catch the iscsi_login_zero_tsih_s1 ->
iscsi_login_set_conn_values call that sets conn->sess then later
kfree(conn->sess) call in the error handling in __iscsi_target_login_thread.
