cherry-pick this commit to master.
Please revert this change.
When loading the consensus from disk, Tor does the protocol check *before*
we do the consensus expiry check:
https://github.com/torproject/tor/blob/b67f3b751a277fb940b155c0bc64f594db5549b0/src/feature/nodelist/networkstatus.c#L1871
Therefore, any Tor that has an old cached consensus, and deploys this
code, will restart in a loop without ever downloading a new consensus.
Thanks to traumschule for this bug report.
