net: mctp: mctp_fraq_queue should take ownership of passed skb

[ Upstream commit 773b27a8a2 ]

As of commit f5d83cf0ee ("net: mctp: unshare packets when
reassembling"), we skb_unshare() in mctp_frag_queue(). The unshare may
invalidate the original skb pointer, so we need to treat the skb as
entirely owned by the fraq queue, even on failure.
