MDEV-26911: Unexpected ER_DUP_KEY, ASAN errors, double free detected in ...

Browse Source 
When loading the histogram, use table->field[N], not table->s->field[N].

When we used the latter we would corrupt the fields's default value. One
of the consequences of that would be that AUTO_INCREMENT fields would
stop working correctly.
