This fixes another error in commit 9e8da0f75731aaa7605cf4656c21ea09e84d2eb1. I neglected to make the mark/restore functionality save and restore the current set of array key values, which led to strange behavior if an IndexScan with ScalarArrayOpExpr quals was used as the inner side of a mergejoin. Per bug #7570 from Melese Tesfaye.
