fix the regression from "direct-io: Fix negative return from dio read beyond eof"
commit 2d4594acbf6d8f75a27f3578476b6a27d8b13ebb upstream.
Sure, it's better to bail out of past-the-eof read and return 0 than return
a bogus negative value on such. Only we'd better make sure we are bailing out
with 0 and not -ENOMEM...
