Thanks for the revision!

I still see a spelling error "udpate" in the commit.  Please fix it.

Instead of using memcpy() to copy a UUID, please use struct assignment
(it is probably not necessary to have a function to do this).

Our usual practice is to write:
  static void
  set_index_row(struct ovsdb_idl_row *row)
instead of:
  static void set_index_row(struct ovsdb_idl_row *row)
