Summary
tipc: fix memory leak in tipc_link_xmit
Details

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

tipc: fix memory leak in tipclinkxmit

In case the backlog transmit queue for system-importance messages is overloaded, tipclinkxmit() 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 tipclinkxmit() returns.
