SUNRPC: Don't return EPROTONOSUPPORT in svc_register()'s helpers

Browse source

The RPC client returns -EPROTONOSUPPORT if there is a protocol version
mismatch (ie the remote RPC server doesn't support the RPC protocol
version sent by the client).

Helpers for the svc_register() function return -EPROTONOSUPPORT if they
don't recognize the passed-in IPPROTO_ value.

These are two entirely different failure modes.

Have the helpers return -ENOPROTOOPT instead of -EPROTONOSUPPORT.  This
will allow callers to determine more precisely what the underlying
problem is, and decide to report or recover appropriately.
