Ranges with step 0, that is, multiple indices representing the same
value, need to report the count exclusively based on indices. This makes
it possible to later retrieve all values, e.g. in a group.

When dealing with groups, the specified window in
linear_range_group_get_win_index can span across multiple groups. In the
current implementation, if maximum value was not in the same sub-window
as the minimum value the function would return -EINVAL. This patch fixes
the problem and updates test cases to cover such scenario.
