4.3-stable review patch. If anyone has any objections, please let me know.

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...
