scsi: target: iscsi: calling iscsit_stop_session() inside iscsit_close_session() has no effect
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.
