ctdb-daemon: Don't mark a node as unhealthy when connecting to it

ctdb-daemon: Don't mark a node as unhealthy when connecting to it

Remote nodes are already initialised as UNHEALTHY when the node list
is initialised at startup (ctdb_load_nodes_file() calls
convert_node_map_to_list()) and when disconnected (ctdb_node_dead()).
So, drop this code.
