read-cache.c: replace `git_config()` with `git_config_get_*()` family 

Use `git_config_get_*()` family instead of `git_config()` to take
advantage of the config-set API which provides a cleaner control flow.

Use an intermediate value, as `version` can not be used directly in
git_config_get_int() due to incompatible type.
