This patch adds a sock->sk_state_change() -> iscsi_target_sk_state_change() callback in order to handle transient TCP failures during the login process, where sock->sk_data_ready() -> iscsi_target_sk_data_ready() may not be called to release connection resources, and relinquish tpg->np_login_lock via iscsit_deaccess_np() It performs the sk->sk_state check using iscsi_target_sk_state_check() to look for TCP_CLOSE_WAIT + TCP_CLOSE, and invokes schedule_delayed_work() -> iscsi_target_do_cleanup() to perform the remaining cleanup from process context. It adds an explicit sk_state_check to iscsi_target_do_login() in order to determine a state failure when iscsi_target_sk_state_change() may not be able to proceed before LOGIN_FLAGS_READY=1 is set. Also use sk->sk_sndtimeo -> sk->sk_rcvtimeo settings during login to iscsi_target_set_sock_callbacks(), and revert back post login to use MAX_SCHEDULE_TIMEOUT in iscsi_target_restore_sock_callbacks().
