ctdb-daemon: Use ctdb_read_nodes() in ctdbd
ctdb_control_getnodesfile() calls ctdb_read_nodes(), which returns a
struct ctdb_node_map rather than the old version, so update associated
marshalling. While here modernise a debug message and wrap the
function arguments.
For ctdb_load_nodes_file() to use ctdb_read_nodes(), tweak
convert_node_map_to_list() to also use the modern node map structure.
Remove unused copy of ctdb_read_nodes_file().
