[PATCH] NFS: readdir reply truncated!

Duh... Even a simple one-liner test can be wrong. The really sad bit
is that I made the same mistake 3 weeks ago, fixed it, and then lost
track of the fix...

To recap fix to fix: A valid end of directory marker has to read
(entry[0]==0 && entry[1]!=0). Here is final correct (I hope) patch.
