nfsd4: zero-length WRITE should succeed
commit fdec6114ee1f0f43b1ad081ad8d46b23ba126d70 upstream.
Zero-length writes are legal; from 5661 section 18.32.3: "If the count
is zero, the WRITE will succeed and return a count of zero subject to
permissions checking".
This check is unnecessary and is causing zero-length reads to return
EINVAL.
