You cannot unblock the days.  This is one of the penalties of cancelling.  https://www.airbnb.com/help/article/990/how-do-host-cancellation-penalties-work

Unfortunately, it doesn't help now, but it would have been better to wait and see if the first guest wanted to extend before accepting another booking for those dates.  I would have contacted the first guest to advise that you were about to accept a booking for those dates and he had to let you know immediately if they were required.  If he failed to respond and then subsequently wanted them after you have given them to the second guest you wouldn't have to cancel anyone, just say that he had left it too late and they were no longer available.  Sorry you are in this position.
