[LTP] [PATCH]utils/sctp: bugfix for testlib/sctputil.h

[Li Min]

The socket is created and bound immediately without waiting for the handshake after close(sk).
"bind(): errno=EADDRINUSE(98): Address already in use" may be reported.
Use SO_REUSEPORT to allow multiple sockets to be bound to the same port.
