tipc: fix skb may be leaky in tipc_link_input
[ Upstream commit 7384b538d3aed2ed49d3575483d17aeee790fb06 ]
When we free skb at tipc_data_input, we return a 'false' boolean.
Then, skb passed to subcalling tipc_link_input in tipc_link_rcv,
<snip>
1303 int tipc_link_rcv:
...
1354 if (!tipc_data_input(l, skb, l->inputq))
1355 rc |= tipc_link_input(l, skb, l->inputq);
</snip>
Fix it by simple changing to a 'true' boolean when skb is being free-ed.
Then, tipc_link_rcv will bypassed to subcalling tipc_link_input as above
condition.
