DDS15 — Read / Take with max_samples = 0

It is not clear what should be done if the user calls read, take, or any of their variants when the following conditions are met:

1. The method is called with max_samples = 0
2. There is data available that would be returned with max_samples > 0

I think we have two options here:

1. Return NO_DATA
2. Return OK with a resulting collection with len = 0

The last sentence of the section seems to indicate the latter...

If the DataReader has no samples that meet the constraints, the return value will be NO_DATA

... but the definition of NO_DATA on page 5 seems to indicate the former (as no data is returned)

Indicates a transient situation where the operation did not
return any data but there is no inherent error.
