wallet: Avoid use of Chain::Lock in CWallet::GetKeyBirthTimes

This is a step toward removing the Chain::Lock class and reducing cs_main
locking.

This change only affects behavior in the case where wallet last block processed
falls behind the chain tip, where it will treat the last block processed as the
current tip.
