Re: [PATCH net] tipc: do not write skb_shinfo frags when doing decrytion

One skb's skb_shinfo frags are not writable, and they can be shared with
other skbs' like by pskb_copy(). To write the frags may cause other skb's
data crash.

So before doing en/decryption, skb_cow_data() should always be called for
a cloned or nonlinear skb if req dst is using the same sg as req src.
While at it, the likely branch can be removed, as it will be covered
by skb_cow_data().
