netfilter: conntrack: fix bug in for_each_sctp_chunk
skb_header_pointer() will return NULL if offset + sizeof(_sch) exceeds
skb->len, so this offset < skb->len test is redundant.
if sch->length == 0, this will end up in an infinite loop, add a check
for sch->length > 0
Fixes: 9fb9cbb1082d ("[NETFILTER]: Add nf_conntrack subsystem.")
