io_uring: ensure that io_init_req() passes in the right issue_flags
We can't use 0 here, as io_init_req() is always invoked with the
ctx uring_lock held. Newer kernels have IO_URING_F_UNLOCKED for this,
but previously we used IO_URING_F_NONBLOCK to indicate this as well.
Fixes: cf7f9cd50013 ("io_uring: add missing lock in io_get_file_fixed")
