9p: saner ->write_end() on failing copy into non-uptodate page If we had a short copy into an uptodate page, there's no reason whatsoever to zero anything; OTOH, if that page had _not_ been uptodate, we must have been trying to overwrite it completely and got a short copy. In that case, overwriting the end with zeroes, marking uptodate and sending to server is just plain wrong. Just unlock, keep it non-uptodate and return 0.
