Resulted from bonding driver registering packet handlers via dev_add_pack and
then trying to call pskb_may_pull. If another packet handler (like for AF_PACKET
sockets) gets called first, the delivered skb will have a user count > 1, which
causes pskb_may_pull to BUG halt when it does its skb_shared check. Fix this by
calling skb_share_check prior to the may_pull call sites in the bonding driver
to clone the skb when needed. Tested by myself and the reported successfully.
