libxt_sctp: fix array out of range in print_chunk
For chunk type ASCONF, ASCONF_ACK and FORWARD_TSN, sctp_chunk_names[].chunk_type
is not equal to the corresponding index in sctp_chunk_names[]. Using this field
leads to a segmentation fault (index out of range).
Example
$ iptables -A INPUT -p sctp --chunk-type all ASCONF,ASCONF_ACK,FORWARD_TSN -j ACCEPT
$ iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Segmentation fault
