3.16.66-rc1 review patch. If anyone has any objections, please let me know.

commit 082aaa8700415f6471ec9c5ef0c8307ca214989a upstream.
When doing reads beyound the end of a file the server returns error STATUS_END_OF_FILE error which is mapped to -ENODATA. Currently we report it as a failure which confuses read stats. Change it to not consider -ENODATA as failure for stat purposes.
