MDEV-31058 ER_KEY_NOT_FOUND upon concurrent CHANGE column autoinc and DML

Browse Source 
When column is changed to autoinc, ALTER TABLE may update zero/NULL values,
if NO_AUTO_VALUE_ON_ZERO mode is not enabled.

Forbid this for LOCK=NONE for the unreliable cases.
The cases are described in online_alter_check_autoinc.
