GEN_NoUserData.seq - Generation of error cause No User Data
To check that if DATA chunk is received with no user data then the
endpoint should send ABORT message with cause No User Data.

Association is established between endpoint A and B. Arrange data
in endpoint A such that DATA chunk with no user data is sent to
endpoint B.

TEST DESCRIPTION:
1. Send DATA chunk from endpoint A to B with no user data i.e. length
should be 16.
2. Check A: ABORT should be received at endpoint A.
3. Check B: Error cause in ABORT is set to "No User Data".

The TSN value field contains the TSN of the DATA chunk received
with no user data field.
This cause code is normally returned in an ABORT chunk (see
Section 6.2).
