Description

In the Linux kernel, the following vulnerability has been resolved:

tipc: fix memory leak in tipc_link_xmit

In case the backlog transmit queue for system-importance messages is overloaded,
tipc_link_xmit() returns -ENOBUFS but the skb list is not purged. This leads to
memory leak and failure when a skb is allocated.

This commit fixes this issue by purging the skb list before tipc_link_xmit()
returns.
