Thread: pgsql: Fix GiST's killing tuple: GISTScanOpaque->curpos wasn't

Log Message:
-----------
Fix GiST's killing tuple: GISTScanOpaque->curpos wasn't
correctly set. As result, killtuple() marks as dead
wrong tuple on page. Bug was introduced by me while fixing
possible duplicates during GiST index scan.
