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.
