Subject: [PATCH 4/7 net-2.6.26] [TIPC]: Remove redundant NULL check when discarding buffers

This patch eliminates a null pointer check when discarding a
TIPC message buffer, since kfree_skb() already handles this
situation.

Acknowledgements to Florian Westphal (fw@...len.de> for
suggesting this enhancement.
