Subject: [PATCH] tipc: fix random link reset problem

In the function tipc_sk_rcv(), the stack variable 'err'
is only initialized to TIPC_ERR_NO_PORT for the first
iteration over the link input queue. If a chain of messages
are received from a link, failure to lookup the socket for
any but the first message will cause the message to bounce back
out on a random link.
We fix this by properly initializing err.
