MDEV-8588/MDEV-19740: Restore a condition

Browse Source 
It looks like the merge of MySQL 5.7.9 to MariaDB 10.2.2 conflicted with
earlier changes that were made in MDEV-8588.

row_search_mvcc(): If the page is corrupted, avoid invoking
btr_cur_store_position(). The caller should not try to fetch
the next record after a hard error.
