unpack_trees(): fix diff-index regression.

When skip_unmerged option is not given, unpack_trees() should not just
skip unmerged cache entries but keep them in the result for the caller to
sort them out.

For callers other than diff-index, the incoming index should never be
unmerged, but diff-index is a special case caller.
