rxrpc: Fix return from none_validate_challenge()
Fix the return value of none_validate_challenge() to be explicitly true
(which indicates the source packet should simply be discarded) rather than
implicitly true (because rxrpc_abort_conn() always returns -EPROTO which
gets converted to true).
Note that this change doesn't change the behaviour of the code (which is
correct by accident) and, in any case, we *shouldn't* get a CHALLENGE
packet to an rxnull connection (ie. no security).
