iSCSI: Logout for a Session

[Matt Wakeley <matt_wakeley@agilent.com>]

Throughout the iSCSI document, it talks about the logout command closing a TCP
connection.  Especially for the purposes of error recover to terminate a TCP
connection and "clean up" so that another TCP connection can be established to
continue the session.  There seems to be no way to indicate that a session is
being terminated.

There should be a flag in the logout command that indicates that the *session*
is being terminated (as well as the TCP connection).
