When creating network portals rapidly, such as when restoring a configuration, LIO's code to reuse existing portals can return a false negative if the thread hasn't run yet and set np_thread_state to ISCSI_NP_THREAD_ACTIVE. This causes an error in the network stack when attempting to bind to the same address/port. This patch sets NP_THREAD_ACTIVE before the np is placed on g_np_list, so even if the thread hasn't run yet, iscsit_get_np will return the existing np.
