Changli Gao ca44ac3861 net: don't reallocate skb->head unless the current one hasn't the needed extra size or is shared 
skb head being allocated by kmalloc(), it might be larger than what
actually requested because of discrete kmem caches sizes. Before
reallocating a new skb head, check if the current one has the needed
extra size.

Do this check only if skb head is not shared.
