As written in doc/iscsi.md, typically the login redirection feature
will be used in scale out iSCSI target system, which runs multiple
SPDK iSCSI target applications.
In scale out iSCSI target system, the initial portal, the current
redirect portal, and the next redirect portal are likely to be in
different SPDK iSCSI target applications.
In this case, asynchronous logout request should be sent independently
from the iSCSI target application which has the current redirect portal.
However, we had added asynchronous logout request into the iSCSI target
application which has the next redirect portal. This idea works only
for the case that login is redirected from the initial portal to a
redirect portal.
We remove asynchronous logout request from iscsi_target_node_redirect()
in this patch, and update the corresponding help documents.
The next patch will add an new RPC to send asynchronous logout
request to all connections to the specified portal group and the
specified target.
