Some RLPX handshake log messages are duplicated (e.g. HelloPacket to <node id>)

I'm testing #5568 and seeing some RLPX handshake messages being logged twice. For example:

DEBUG 04-14 21:58:07 p2p  rlpx   p2p.connect.egress: HelloPacket to ##a979fb57…@52.16.188.185:30303
DEBUG 04-14 21:58:07 p2p  rlpx   p2p.connect.egress: HelloPacket to ##865a6325…@52.176.100.77:30303
DEBUG 04-14 21:58:07 p2p  rlpx   p2p.connect.egress: HelloPacket to ##865a6325…@52.176.100.77:30303
DEBUG 04-14 21:58:07 p2p  rlpx   p2p.connect.egress: Frame header from ##a979fb57…@52.16.188.185:30303
DEBUG 04-14 21:58:07 p2p  rlpx   p2p.connect.egress: HelloPacket to ##158f8aab…@13.75.154.138:30303
DEBUG 04-14 21:58:07 p2p  rlpx   p2p.connect.egress: Frame header from ##865a6325…@52.176.100.77:30303
DEBUG 04-14 21:58:07 p2p  rlpx   p2p.connect.egress: Frame header from ##865a6325…@52.176.100.77:30303

I don't think this is a regression in the PR since the changes don't affect the logging logic.

I'm not seeing this anymore, I suspect this was caused by us having multiple RLPX handshakes in progress with the same node (which was fixed by #5599) . Will re-activate if this pops up again.
