[PATCH 11/17] dasd: also call __invalidate_device when setting the device offline

[Christoph Hellwig <hch@lst.de>]

Don't just write out the data, but also invalidate all caches when setting
the device offline.  Stop canceling the offlining when writeback fails
as there is no way to recover from that anyway.
