Revert "GridLayoutManager: fix bug if current focus is on top of grid view"

This reverts commit bcb7bf9b051050fa44ae270b4ac0ecab5456fe33.

That change caused issue that press DOWN in last item of fast lane will focus
to right side by default focusfinder.  We have to revert this issue.  To focus
on widget overlaid on top of RowsFragment, user has to override focusSearch()
in a customized widget like BrowseFragment does.
