OotbShutWithZeroLength.seq - OOTB SHUTDOWN chunk is received with chunk length set to zero
To check that if OOTB SHUTDOWN chunk is received with chunk length set to
zero, the endpoint should response with ABORT message and error cause is
set to Protocol Violation.

Association is not established between endpoint A and B. Arrange data
in endpoint A such that SHUTDOWN chunk with chunk length set to zero
is sent to endpoint B.

TEST DESCRIPTION:
1. From endpoint A, send valid SHUTDOWN message to endpoint B,
when there is no association between them.
2. Check A: ABORT should be received at endpoint A.
3. Check B: Error cause in ABORT is set to "Protocol Violation".
4. Check C: Remote System not enter dead loop.

8.4. Handle "Out of the Blue" Packets
An SCTP packet is called an "out of the blue" (OOTB) packet if it is
correctly formed (i.e., passed the receiver's CRC32c check; see
Section 6.8), but the receiver is not able to identify the
association to which this packet belongs.
The receiver of an OOTB packet MUST do the following:
1) If the OOTB packet is to or from a non-unicast address, a
receiver SHOULD silently discard the packet. Otherwise,
