block: Introduce blk_queue_flag_{set,clear,test_and_{set,clear}}()
Introduce functions that modify the queue flags and that protect these modifications with the request queue lock. Except for moving one wake_up_all() call from inside to outside a critical section, this patch does not change any functionality.
