LU-13666 lod: update .do_index_ops on layout detach

Directory migration detaches stripes from source, and then attaches
them to target if source is a striped directory. This will convert
source from striped directory to plain directory, it needs update
.do_index_ops from lod_striped_index_ops to lod_index_ops to avoid
trigger assertion in index ops.
