Problem: DECIMAL columns in I_S must be explicitly set of some value. I_S columns do not have `DEFAULT 0` (after MDEV-18918), so during restore_record() their record fragments pointed by Field::ptr are initialized to zero bytes 0x00. But an array of 0x00's is not a valid binary DECIMAL value. So val_decimal() called for such Field_new_decimal generated a warning when seeing a wrong binary encoded DECIMAL value in the record. Fix: Explicitly setting INFORMATION_SCHEMA.PROCESSLIST.PROGRESS to the decimal value of 0 if no progress information is available.
