Take an extra reference on a device insert. So devices keep around in the cache until nfs_client release. (This was the behavior of the old cache) The extra reference will be removed in nfs4_deviceid_purge_client(). I tested this and it works perfectly. TODO: Define an nfs4_get_deviceid() Currently accesing did->ref directly TODO: nfs4_insert_deviceid_node should check if there are too many devices and start purging them. Say by time from last use.
