Davide Caratti f3c0eb05e2 netfilter: conntrack: fix false CRC32c mismatch using paged skb 
sctp_compute_cksum() implementation assumes that at least the SCTP header
is in the linear part of skb: modify conntrack error callback to avoid
false CRC32c mismatch, if the transport header is partially/entirely paged.

Fixes: cf6e007eef83 ("netfilter: conntrack: validate SCTP crc32c in PREROUTING")
