Trond Myklebust 2446ab6070 SUNRPC: Use RCU to dereference the rpc_clnt.cl_xprt field 
A migration event will replace the rpc_xprt used by an rpc_clnt.  To
ensure this can be done safely, all references to cl_xprt must now use
a form of rcu_dereference().

Special care is taken with rpc_peeraddr2str(), which returns a pointer
to memory whose lifetime is the same as the rpc_xprt.
