Prevent hang in git cat-file if the repository is not a valid repository (Partial #17991) (#17992)

Browse source 
* Prevent hang in git cat-file if the repository is not a valid repository (Partial #17991)

Unfortunately it appears that if git cat-file is run in an invalid
repository it will hang until stdin is closed. This will result in
deadlocked /pulls pages and dangling git cat-file calls if a broken
repository is tried to be reviewed or pulls exists for a broken
repository.
