With the newly introduced helper functions the skb pulling is hidden in
the checksumming function - and undone before returning to the caller.
The IGMPv3 and MLDv2 report parsing functions in the bridge still
assumed that the skb is pointing to the beginning of the IGMP/MLD
message while it is now kept at the beginning of the IPv4/6 header,
breaking the message parsing and creating packet loss.
Fixing this by taking the offset between IP and IGMP/MLD header into
account, too.
Fixes: 9afd85c9e455 ("net: Export IGMP/MLD message validation code")
