net, scsi/csgb4i: convert skb->transport_header into skb_transport_header(skb)

The change set of 1a37e412, "net: Use 16bits for *_headers fields
of struct skbuff" converted from sk_buff_data_t into 16bit integer.
So skb->tail needs to be converted to skb_tail_pointer(skb).

Found by inspection. Compile tested only.
