Most files in the 'nfsd' filesystem are transactional.
When you write, a reply is generated that can be read back
only on the same 'file'.
If the reply has zero length, the 'write' will incorrectly
return a value of '0' instead of the length that was
written. This causes 'rpc.nfsd' to give an annoying warning.
This patch fixes the test.
