btrfs: simplify setting/clearing fs_info to btrfs_fs_devices
It makes no sense to have sysfs-related routines be responsible for properly initialising the fs_info pointer of struct btrfs_fs_device. Instead this can be streamlined by making it the responsibility of btrfs_init_devices_late to initialize it. That function already initializes fs_info of every individual device in btrfs_fs_devices. As far as clearing it is concerned it makes sense to move it to close_fs_devices. That function is only called when struct btrfs_fs_devices is no longer in use - either for holding seeds or main devices for a mounted filesystem.
