hs-v3: Relax severity of a log message when decoding descriptors.

Make it LOG_PROTOCOL_WARN and also add the expiration timestamp in there to
ease debugging in the future.
parent e4727372
o Minor bugfixes (onion services v3):
- Relax severity of a log message that can appear naturally when decoding
onion service descriptors as a relay. Also add some diagnostics to debug
any future bugs in that area. Fixes bug 31669; bugfix on
