In github, the easy way is to delete the remote branch in the github UI, under branches tab. You have to make sure remove following settings to make the branch deletable:

1. Not a default branch
2. No opening poll requests.
3. The branch is not protected.

Now recreate it in your local repository to point to the previous commit point. and add it back to remote repo.

Then push the local branch to remote

git push -u origin master

Add back the default branch and branch protection, etc.
