[PATCH] RPC: Make rpc_create_client() probe server for RPC program+version support
Ensure that we don't create an RPC client without checking that the server
does indeed support the RPC program + version that we are trying to set up.
This enables us to immediately return an error to "mount" if it turns out
that the server is only supporting NFSv2, when we requested NFSv3 or NFSv4.
