channeld: don't close connection on invalid badonion code (LND bug?)

Browse Source 
```
channeld WARNING: Bad update_fail_malformed_htlc failure code 4103
```

Warren Togami reports this happening with Bitrefill on every reconnect,
so it's clearly something LND does.

(4103 is TEMPORARY_CHANNEL_FAILURE, which does not belong in update_fail_malformed_htlc).

Changelog-Changed: Protocol: We allow update_fail_malformed_htlc with invalid error codes (LND?)
