Avoid that sparse reports the following complaints:

block/elevator.c:541:29: warning: incorrect type in assignment (different base types)
block/elevator.c:541:29:    expected bool [unsigned] [usertype] next_sorted
block/elevator.c:541:29:    got restricted req_flags_t

block/blk-mq-debugfs.c:92:54: warning: cast from restricted req_flags_t
