sctp: fix to choose alternate destination when retransmit ASCONF chunk
RFC 5061 Section 5.1 ASCONF Chunk Procedures said:
B4) Re-transmit the ASCONF Chunk last sent and if possible choose an
alternate destination address (please refer to [RFC4960],
Section 6.4.1). An endpoint MUST NOT add new parameters to this
chunk; it MUST be the same (including its Sequence Number) as
the last ASCONF sent. An endpoint MAY, however, bundle an
additional ASCONF with new ASCONF parameters with the next
Sequence Number. For details, see Section 5.5.
This patch fix to choose an alternate destination address when
re-transmit the ASCONF chunk, with some dup codes cleanup.
