instead rely on the quick return of read_index_from which has
    /* istate->initialized covers both .git/index and .git/sharedindex.xxx */
    if (istate->initialized)
        return istate->cache_nr;

such that we do not have memory leaks or other issues. Currently we do not have a lot of callers, such that we can change the contract of the 'repo_read_index' function easily. However going through all the callers and then looking at the implementation, may hint at a desire to have repo_read_index documented in repository.h (There is a hint in struct repository, that its field index can be initialized using repo_read_index, but what does repo_read_index actually do?)
