NFS: Ensure O_DIRECT reports an error if the bytes read/written is 0
If the attempt to resend the I/O results in no bytes being read/written, we must ensure that we report the error. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com> Fixes: 0a00b77b331a ("nfs: mirroring support for direct io") Cc: stable@vger.kernel.org # v3.20+
