LL/CON/MAS/BV-74-C: no verification if parameters are set correctly

[kruithofa]

The DLE control procedure is called with different length & timing parameters.
An event is generated by the HCI returning the actual length & timing settings used.

The test needs to verify that the returned values are correct

Note: This causes the test to pass in EDTT but it is failing in EBQ

[kruithofa]

There is some verification of parameters in the routine that receives the event-results, but this is very generic, and probably not strict enough; some further investigation is required
