bcache: recal cached_dev_sectors on detach
[ Upstream commit 46010141da6677b81cc77f9b47f8ac62bd1cbfd3 ]
Recal cached_dev_sectors on cached_dev detached, as recal done on
cached_dev attached.
Update the cached_dev_sectors before bcache_device_detach called
as bcache_device_detach will set bcache_device->c to NULL.
