Fix race condition in clientid expiration during compound operations Add reference counting for data->preserved_clientid to prevent the clientid structure from being freed while still in use during NFSv4 compound operations. The crash occurred when a clientid expired while a compound operation was still using it, causing update_lease_simple() to acquire a mutex on a freed clientid structure.
