[PATCH RESEND 3/3] iscsi target: calling iscsit_stop_session() inside iscsit_close_session() has no

[Maurizio Lombardi <mlombard@redhat.com>]

iscsit_close_session() can only be called when nconn is zero (otherwise
a kernel panic is triggered); if nconn is zero then
iscsit_stop_session() does nothing and exits, so calling it
makes no sense.

We still need to call iscsit_check_session_usage_count() because
this function will sleep if the session's refcount is not zero and
we don't want to destroy the session structure if
it's still being referenced.
