  1. LUCENE-9565 Fix competitive iteration 

    PR apache#1351 introduced a sort optimization where documents can be skipped.
But iteration over competitive iterators was not properly organized,
as they were not storing the current docID, and
when competitive iterator was updated the current doc ID was lost.

This patch fixed it.

Relates to apache#1351
