Xin Long adbce6d20d tipc: fix a possible memleak in tipc_buf_append
[ Upstream commit 97bf6f81b29a8efaf5d0983251a7450e5794370d ]

__skb_linearize() doesn't free the skb when it fails, so move
'*buf = NULL' after __skb_linearize(), so that the skb can be
freed on the err path.

Fixes: b7df21cf1b79 ("tipc: skb_linearize the head skb when reassembling msgs")
