tipc: correct initialization of skb list

Jon Maloy · davem330 · commit 3382605fd8db · 2017-10-08T21:13:23.000-07:00
We change the initialization of the skb transmit buffer queues
in the functions tipc_bcast_xmit() and tipc_rcast_xmit() to also
initialize their spinlocks. This is needed because we may, during
error conditions, need to call skb_queue_purge() on those queues
further down the stack.
