btrfs-progs: mkfs seg fault for wrong free 

With commit
        87c09f7 Btrfs-progs: fix memory leaks on cleanup

mkfs on multiple dev is ending with segfault at
close_all_devices() during kfree(device->name)

because mkfs calls btrfs_add_to_fsid, which does not initialize
name when dev is added to the list.
