NFSv4 reserves readdir cookie values 0-2 for special entries (. and ..),
but jfs allows a value of 2 for a non-special entry. This incompatibility
can result in the nfs client reporting a readdir loop.
This patch doesn't change the value stored internally, but adds one to
the value exposed to the iterate method.
