Fix reset of incorrect hash iterator in GROUPING SETS queries
This fixes an unlikely issue when fetching GROUPING SET results from
their internally stored hash tables. It was possible in rare cases that
the hash iterator would be set up incorrectly which could result in a
crash.
This was introduced in 4d143509c, so backpatch to v18.
Many thanks to Yuri Zamyatin for reporting and helping to debug this
issue.
