crimson/os/seastore/cache: Cache::get_(del)_backrefs_in_range return extents in half...

Change Cache::get_(del)_backrefs_in_range's return from extents in [start,end] to extents in
[start, end); this is because BackrefManager::get_mappings return extents in [start,end), and
Cache's related methods have to be consistent with BackrefManager::get_mappings
