bcache: move calc_cached_dev_sectors to proper place on backing device detach

Calculation of cache_set's cached sectors is done by travelling
cached_devs list as shown below:

static void calc_cached_dev_sectors(struct cache_set *c)
{
...
        list_for_each_entry(dc, &c->cached_devs, list)
                sectors += bdev_sectors(dc->bdev);

        c->cached_dev_sectors = sectors;
}

But cached_dev won't be unlinked from c->cached_devs list until we call
following list_move(&dc->list, &uncached_devices),
so previous fix in 'commit 46010141da6677b81cc77f9b47f8ac62bd1cbfd3
("bcache: recal cached_dev_sectors on detach")' is wrong, now we move
it to its right place.
