Jens Axboe 3e69426da2 io_uring: punt even fadvise() WILLNEED to async context
Andres correctly points out that read-ahead can block, if it needs to
read in meta data (or even just through the page cache page allocations).
Play it safe for now and just ensure WILLNEED is also punted to async
context.

While in there, allow the file settings hints from non-blocking
context. They don't need to start/do IO, and we can safely do them
inline.

Fixes: 4840e418c2 ("io_uring: add IORING_OP_FADVISE")
