I think the code is fine, but I think it might be best to call this
"ITER_FLAG_NOIO" or something like that.

The "FAST_ONLY" name makes sense in the context of
"get_user_pages_fast()" where we have that "fast" naming (and the long
history too). But I don't think it makes much sense as a name in the
context of iov_iter.
