MySQL Bugs: #119280: INSTANT ADD succeeds even when the size of a row crosses row_size

Bug #119280	INSTANT ADD succeeds even when the size of a row crosses row_size_limit

Description:
The INSTANT ADD operation may report success even when the maximum possible row size exceeds the limit. This inconsistency occurs because the fixed_len attribute of the dummy_field is improperly set, which is used to calculate the maximum field size. This miscalculation can lead to an unexpected database crash in a rollback operation.
