Bug Description

When node's own IP address is defined in in wsrep_cluter_address

     wsrep_cluster_address=gcomm://OWN_IP,other,nodes

the node is blacklisting itself

     [Warning] WSREP: (cd1938a2, 'tcp://0.0.0.0:4567') address 'tcp://192.168.1.14:4567' points to own listening address, blacklisting

however later is trying to connect itself:

     [Note] WSREP: (cd1938a2, 'tcp://0.0.0.0:4567') connection to peer cd1938a2 with addr tcp://192.168.1.14:4567 timed out, no messages seen in PT3S

An output of `ip a l`:

# ip a l

Tested against PXC 5.7.19-29.22.3 and PXC 5.6.37-26.21-3.

The node is reporting that it hasn't heard from that address in 3 seconds (gmcast.peer.timeout), which is valid since that address has been blacklisted.

The issue would be that the liveness check is reporting on blacklisted entries.
