Subject: [PATCH] nfsd: Ensure stateids remain unique until they are freed

Add an extra delegation state to allow the stateid to remain in the idr
tree until the last reference has been released. This will be necessary
to ensure uniqueness once the client_mutex is removed.

[jlayton: reset the sc_type under the state_lock in unhash_delegation]
