tipc: fix wrong notification node addresses 

The previous bug fix had an unfortunate side effect that broke
distribution of binding table entries between nodes. The updated
tipc_sock_addr struct is also used further down in the same
function, and there the old value is still the correct one.

Fixes: 032062f363 ("tipc: fix wrong publisher node address in link publications")
