SUNRPC: Add a helper to apply a function to all the rpc_clnt's transports
Add a helper for tasks that require us to apply a function to all the transports in an rpc_clnt. An example of a usecase would be BIND_CONN_TO_SESSION, where we want to send one RPC call down each transport. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
