Title: CFilters reject and disconnect peers with a valid block hash
Description: ### Is there an existing issue for this? - [X] I have searched the existing issues ### Current behaviour For quite some time now, I've noticed that neutrino clients connected to my Bitcoin Core instance would have issues connecting after a while. Today, I turned on debug logging for `[net]` and discovered these messages (see log section). Peers were being disconnected! But strangely, it seems like even though these peers are requesting valid block hashes, Bitcoin Core is rejecting the serving of CFilters to them. No other disconnect messages for CFilters have been observed. I checked validity two ways: by checking against bitcoin-cli getblock as well as using a block explorer (mempool.space). ### Expected behaviour If a BIP-157 client requests a valid block hash as set forth by `BlockRequestAllowed`, it should receive a response from Bitcoin Core. ### Steps to reproduce 1. Setup Bitcoin Core node with `peerbloomfilters=1` and `peerblockfilters=1`, ensure port `8333` is open. Also set `debug=net` for debug level for networking logs. 2. Connect neutrino peer to Bitcoin Core node and wait. 3. Eventually, you will see the debug network message above. ### Relevant log output ``` 2024-03-14T16:25:48Z [net] received: getcfheaders (37 bytes) peer=35 2024-03-14T16:25:48Z [net] peer 35 requested
