Pablo Neira Ayuso d5953d680f netfilter: nft_payload: sanitize offset and length before calling skb_checksum() 
If access to offset + length is larger than the skbuff length, then
skb_checksum() triggers BUG_ON().

skb_checksum() internally subtracts the length parameter while iterating
over skbuff, BUG_ON(len) at the end of it checks that the expected
length to be included in the checksum calculation is fully consumed.

Fixes: 7ec3f7b47b ("netfilter: nft_payload: add packet mangling support")
