SUNRPC: remove RPC client pipefs dentries after unregister

Without this patch we have races:

rpc_fill_super rpc_free_client
rpc_pipefs_event(MOUNT) rpc_remove_pipedir
spin_lock(&rpc_client_lock);
rpc_setup_pipedir_sb
spin_unlock(&rpc_client_lock);
spin_lock(&rpc_client_lock);
(remove from list)
spin_unlock(&rpc_client_lock);
MEAMORY LEAKED
