When performing block import we might refuse to import a block until some previous block justifications are imported (#7321). With the current implementation we will restart the sync process after getting a block import error. In this case, we will drop all in-flight sync requests and figure out new block requests for each peer. This leads to a situation where we are constantly restarting sync and are unable to download the justifications that would eventually fix the block import error. This PR changes the sync logic so that when restarting it peers that were doing any kind of finality related request (downloading justifications or finality proofs) keep their existing state.
