iscsi-target: Fix iscsit_transport reference leak during NP thread reset
This patch fixes a bug in __iscsi_target_login_thread() where an explicit
network portal thread reset ends up leaking the iscsit_transport module
reference, along with the associated iscsi_conn allocation.
This manifests itself with iser-target where a NP reset causes the extra
iscsit_transport reference to be taken in iscsit_conn_set_transport()
during the reset, which prevents the ib_isert module from being unloaded
after the NP thread shutdown has finished.
