Reorder the xe_sched_tdr_queue_imm and set_exec_queue_banned calls in guc_exec_queue_stop. This prevents a possible race condition between the two events in which it's possible for xe_sched_tdr_queue_imm to wake the ufence waiter before the exec queue is banned, causing the ufence waiter to miss the banned state.
