NFSv4: Avoid unnecessary scans of filesystems for returning delegations
The amount of looping through the list of delegations is occasionally
leading to soft lockups. If the state manager was asked to return
delegations asynchronously, it should only scan those filesystems that
hold delegations that need to be returned.
