Now that all XDR decoder routines use xdr_streams, there should be no need
to support the legacy calling sequence (rpc_rqst, __be32 *, RPC res) anywhere.
We can construct the xdr_stream with xdr_init_decode() in the generic RPC code,
instead of in each decoder function.
This is a refactoring change. It should not cause different behavior.
