[SCSI] scsi_transport_iscsi: Add conn login, kernel to user, event to support offload session login. Offload drivers like qla4xxx will offload the sending of the login/logout pdus still, so this patch adds iscsi_conn_login_event which is used by these types of drivers to notify userspace that the connection has changed state. It also adds a iscsi_is_session_online helper so the lld can query the sessions state field. Signed-off-by:Manish Rangankar <manish.rangankar@qlogic.com> Signed-off-by:
