nfsd4: introduce nfs4_client.cl_refcount
Currently just initialize the cl_refcount to 1 and decrement in expire_client(), conditionally freeing the client when the refcount reaches 0. To be used later by nfsv4.1 compounds to keep the client from timing out while in use. Signed-off-by: Benny Halevy <bhalevy@panasas.com> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
