OOTB_StaleCookieErrorChunk.seq - ERROR chunk with Stale Cookie ERROR is received from an address with which endpoint has no association
To check that if ERROR chunk with Stale Cookie ERROR is received
from an address with which endpoint has no association, the
enpoint should silently discard the packet.

Association is not established between endpoint A and B. Arrange the data
in endpoint A such that ERROR chunk with Stale Cookie ERROR is sent to
endpoint B.

COOKIE-ACK ----------------> Silently discard
(with Stale Cookie ERROR)
TEST DESCRIPTION:
1. Send ERROR message with Stale Cookie ERROR from endpoint A to B,
when there is no association between them.
2. Check A: ERROR message with Stale Cookie ERROR will be discarded.
3. Check B: State of endpoint B is not disturbed.

RFC 4960
8.4. Handle "Out of the Blue" Packets
6) If the packet contains a SHUTDOWN COMPLETE chunk, the receiver
should silently discard the packet and take no further action.
Otherwise,
7) If the packet contains a "Stale Cookie" ERROR or a COOKIE ACK,
the SCTP packet should be silently discarded. Otherwise,
8) The receiver should respond to the sender of the OOTB packet with
an ABORT. When sending the ABORT, the receiver of the OOTB
packet MUST fill in the Verification Tag field of the outbound
packet with the value found in the Verification Tag field of the
OOTB packet and set the T bit in the Chunk Flags to indicate that
the Verification Tag is reflected. After sending this ABORT, the
receiver of the OOTB packet shall discard the OOTB packet and
take no further action.
