EMF+ records don't need payload all the time
EMF+ records don't need payload all the time

Fix for fdo#39517. Looking through the emf+ records, it looks like the
assumption made that the minimum valid record length is 12 + non-0
length payload isnt' right, looks like that the minimum valid record
length is just 12, i.e. no need for a payload.
