The specification recommends using a length of 256 for onion errors, but it doesn't say that we should reject errors that use a different length. We may want to start creating errors with a bigger length than 256 if we need to transmit more data to the sender. In order to prepare for this, we keep creating 256-bytes onion errors, but allow receiving errors of arbitrary length. See the specification here: lightning/bolts#1021 Fixes #2438
