Cong Wang 1148831a79 bonding: validate ip header before check IPPROTO_IGMP 
[ Upstream commit 9d1bc24b52 ]

bond_xmit_roundrobin() checks for IGMP packets but it parses
the IP header even before checking skb->protocol.

We should validate the IP header with pskb_may_pull() before
using iph->protocol.
