Fix xdr.h lvalue casts

[Andreas Jaeger]

This fixes the last lvalue as cast problem in glibc when I compile on
AMD64 (I'll double check later that I didn't miss anything).

I tested that the patch generates the same code as the old code on one
file (sunrpc/rpc_cmsg.o) compiling for amd64.

The patch was done by Joseph.

Ok to commit?

	* sunrpc/rpc/xdr.h (IXDR_GET_LONG, IXDR_PUT_LONG): Do not use
	casts as lvalues.
