iscsi-target: Fix incorrect np->np_thread NULL assignment
When shutting down a target there is a race condition between iscsit_del_np() and __iscsi_target_login_thread(). The latter sets the thread pointer to NULL, and the former tries to issue kthread_stop() on that pointer without any synchronization. This patch moves the np->np_thread NULL assignment into iscsit_del_np(), after kthread_stop() has completed. It also removes the signal_pending() + np_state check, and only exits when kthread_should_stop() is true.
