libdevmapper logging not properly initialized

        dm_init();
        if (getuid() != 0) {
                fprintf(stderr, "need to be root\n");
                exit(1);
        }
        /* make sure we don't lock any path */
        chdir("/");
        umask(umask(077) | 022);
        conf = alloc_config();

dm_init is called before allocating conf. But dm_init depends on conf->verbosity to initialize libdevmapper logging. In the current situation, the verbosity is always set to 0 because conf is 0.

extern void
dm_init(void) {
        dm_log_init(&dm_write_log);
        dm_log_init_verbose(conf ? conf->verbosity + 3 : 0);
}
