sctp: discard ABORT chunk with zero verification tag in COOKIE-WAIT state

In current implementation if ABORT chunk is received with T flag is set
and zero verification tag in COOKIE-WAIT state, the ABORT chunk will be
always accepted. This is because in COOKIE-WAIT state, the endpoint does
not know the peer's verification tag, and it's zero in the endpoint.
