io_uring: fix invalid flags for io_put_kbuf()

Browse source

io_req_complete_failed() doesn't require callers to hold ->uring_lock,
use IO_URING_F_UNLOCKED version of io_put_kbuf(). The only affected
place is the fail path of io_apoll_task_func(). Also add a lockdep
annotation to catch such bugs in the future.
