[PATCH] xfrm: init skb_head lock for transport-mode packets

[Artem Savkov]

Commit acf568ee859f "xfrm: Reinject transport-mode packets through tasklet"
adds an sk_buff_head queue, but never initializes trans->queue.lock, which
results in a "spinlock bad magic" BUG on skb_queue_tail() call in
xfrm_trans_queue.
Use skb_queue_head_init() instead of __skb_queue_head_init() to properly
initialize said lock.
