tipc: update mon's self addr when node addr generated
commit 46cb01eeeb86fca6afe24dda1167b0cb95424e29 upstream. In commit 25b0b9c4e835 ("tipc: handle collisions of 32-bit node address hash values"), the 32-bit node address only generated after one second trial period expired. However the self's addr in struct tipc_monitor do not update according to node address generated. This lead to it is always zero as initial value. As result, sorting algorithm using this value does not work as expected, neither neighbor monitoring framework. In this commit, we add a fix to update self's addr when 32-bit node address generated.
