3109a1f948 refactor: Avoid locking cs_main in ProcessNewBlockHeaders (João Barbosa)

Pull request description:

  Builds on #16774, this change avoids locking `cs_main` in `ProcessNewBlockHeaders` when the tip has changed - in this case the removed lock was necessary to just log a message.

Top commit has no ACKs.
