The patch below modifies skb_unlink() to not use skb->link anymore.
skb_unlink() appears in the Rx path (zatm.c::poll_rx()). The Rx skb
pool is managed in zatm.c::refill_pool(): the single alloc_skb() of
the whole driver and its associated skb_queue_tail appear in
zatm.c::refill_pool().
Compilation issues the same warning before and after the patch.
