repo_read_index: don't discard the index
Have 'repo_read_index()' behave more like the other read_index family of
functions and don't discard the index if it has already been populated
and 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;
