RDS module sits on top of TCP (rds_tcp) and IB (rds_rdma), so messages
arrive in form of skb (over TCP) and scatterlist (over IB/RDMA).
However, because socket filter only deal with skb (e.g. struct skb as
bpf context) we can only use socket filter for rds_tcp and not for
rds_rdma.
Considering one filtering solution for RDS, it seems that the common
denominator between sk_buff and scatterlist is scatterlist. Therefore,
this patch converts skb to sgvec and invoke sg_filter_run for
rds_tcp and simply invoke sg_filter_run for IB/rds_rdma.
