Bug #46159: simple query that never returns
The external 'for' loop in remove_dup_with_compare() handled
HA_ERR_RECORD_DELETED by just starting over without advancing
to the next record which caused an infinite loop.
This condition could be triggered on certain data by a SELECT
query containing DISTINCT, GROUP BY and HAVING clauses.
Fixed remove_dup_with_compare() so that we always advance to
the next record when receiving HA_ERR_RECORD_DELETED from
rnd_next().
