This is a cleanup patch. Such helpers like nfs_cache_init() and nfs_cache_destroy() are redundant, because they are just a wrappers around sunrpc_init_cache_detail() and sunrpc_destroy_cache_detail() respectively. So let's remove them completely and move corresponding logic to nfs_cache_register_net() and nfs_cache_unregister_net() respectively (since they are called together anyway).
