MDEV-22284 Aria table key read crash because wrong index usedbb-10.2-midenok2
When restoring lastinx last_key.keyinfo must be updated as well. The
good example is in _ma_check_index().
The point of failure is extra(HA_EXTRA_NO_KEYREAD) in
ha_maria::get_auto_increment():
1. extra(HA_EXTRA_KEYREAD) saves lastinx;
2. maria_rkey() changes index, so the lastinx and last_key.keyinfo;
3. extra(HA_EXTRA_NO_KEYREAD) restores lastinx but not
last_key.keyinfo.
So we have discrepancy between lastinx and last_key.keyinfo after 3.
