SKB_FCLONE_UNAVAILABLE has overloaded meaning depending on type of skb. 1: If skb is allocated from head_cache, it indicates fclone is not available. 2: If skb is a companion fclone skb (allocated from fclone_cache), it indicates it is available to be used. To avoid confusion for case 2 above, this patch replaces SKB_FCLONE_UNAVAILABLE with SKB_FCLONE_FREE where appropriate. For fclone companion skbs, this indicates it is free for use. SKB_FCLONE_UNAVAILABLE will now simply indicate skb is from head_cache and cannot / will not have a companion fclone.
