Maybe a dumb question, but what's the practical difference. The only change my eye can spot is changing an if let to a match that only matches on the same one case.

The Ok arm of the match statement added another condition as well if remaining_fragments.len() < last_remaining_fragments.len() -- this line

xcmp-queue: Fix handling of encoded blobs
2c54ba7 
With #701 we tried to fix some infinite loop related to encoded blobs, however that lead actually to
not being able to process encoded blobs at all. The reason for this is that `decode_all` doesn't
consume the given input. The point of this function is that it returns an error if the data couldn't
be decoded or there is still data left. However, this means that the check
`remaining_fragments.len() < last_remaining_fragments.len()` would always fail.

We remove the while loop, because we decode the entire fragment anyway or it fails. Aka, we don't
need to loop here. Next we remove the broken check and we directly reset the
`remaining_fragments` (because `decode_all` doesn't consume anything).

need to loop here. Next we remove the broken check and we directly reset the
`remaining_fragments` (because `decode_all` doesn't consume anything).

* Restore correct behavior

We need to use a while loop, because there can be multiple `Vec<u8>`s. We also need to use `decode`,
because `decode_all` would otherwise return an error if the input is not empty afterwards.

* Remove unused import
