SUNRPC: Rename xs_encode_tcp_fragment_header()

Clean up: Use a more generic name for xs_encode_tcp_fragment_header();
it's appropriate to use for all stream transport types.  We're about
to add new stream transport.

Also, move it to a place where it is more easily shared amongst the
various send_request methods.  And finally, replace the "htonl" macro
invocation with its modern equivalent.
