    Description

      We used llapi_get_obd_count() to get MDT/OST counts, which call LL_IOC_GETOBDCOUNT
      internally.

      However, we return lmv->lmv_mdt_descs.ltd_tgts_size as MDT count, this is not right.
      @ltd_tgts_size could be larger than actual MDT count, as we preallocate ltd_tgts and resize it if necessary.
