netfilter: bridge: set skb transport_header before entering NF_INET_PRE_ROUTING
Since Commit 21d1196a35f5 ("ipv4: set transport header earlier"),
skb->transport_header has been always set before entering INET
netfilter. This patch is to set skb->transport_header for bridge
before entering INET netfilter by bridge-nf-call-iptables.
It also fixes an issue that sctp_error() couldn't compute a right
csum due to unset skb->transport_header.
Fixes: e6d8b64b34aa ("net: sctp: fix and consolidate SCTP checksumming code")
