Subject: sunrpc: fix error path in module_init
From: Akinobu Mita <[EMAIL PROTECTED]>
register_rpc_pipefs() needs to clean up rpc_inode_cache
by kmem_cache_destroy() on register_filesystem() failure.
init_sunrpc() needs to unregister rpc_pipe_fs by unregister_rpc_pipefs()
when rpc_init_mempool() returns error.
