The server name is expected to be a null-terminated string, so we can't
pass in the raw client identifier.
What's more, the client identifier is just a binary, not necessarily
printable, blob. Let's just use the ip address instead. The server
name appears to exist just to help debugging by making some printk's
more informative.
Note that the string is copies into the rpc client structure, so
the pointer to the local variable does not outlive the function call.
