[PATCH 02/10] object-file API: return "void", not "int" from hash_object_file()

<patch-02.10-ab1d204f49b-20220201T144803Z-avarab@gmail.com>
In-Reply-To

The hash_object_file() function added in abdc3fc8421 (Add hash_sha1_file(), 2006-10-14) did not have a meaningful return value, and it never has.

One was seemingly added to avoid adding braces to the "ret = " assignments being modified here. Let's instead assign "0" to the "ret" variables at the beginning of the relevant functions, and have them return "void".
