rpc: transport may be destroyed while rpc isn't
rpc_clnt object is destroyed after the corresponding transport object is
destroyed. But rpc_clnt_reconnect, a timer driven function, refers to
the transport object beyond its 'life'. Instead, using the embedded
connection object prevents use after free problem wrt transport object.
Also, access transport object under conn->lock.
