When a repository is broken but git repository could be open, then mark it as normal

[lunny]

Some repositories will be marked as broken because of temporary disk access problems and can not be recovered except to update the database.

This PR will mark a broken repository as normal if the git repository could be open normally.

Try to fix #34424

I do not think you should patch it again.

Recently, because of the lack of hard disk space on my gitea server, I took a backup of all my gitea data via scp, but when I restore gitea again via scp, I get the same type of situation, and opening the repository gives me an error: "The Git data underlying this repository cannot be read. Contact the administrator of this instance or delete this repository.", part of the repository has this problem, if you query the repository directly from the database with a status of 3, you can't find a single piece of data. Only when you open a repository on the web page with this error, and then go to the database to query the status of 3 can be found, my solution is to write a script to re-initialize all the repositories (git init ---bare) once, and if the punch card repository in the emergence of this problem, then manually change the status of the database from 3 to 0.

I've been busy with work lately, so I may not have time to look at it.
