filesystem-dax: convert to dax_direct_access()
Now that a dax_device is plumbed through all dax-capable drivers we can switch from block_device_operations to dax_operations for invoking ->direct_access. This also lets us kill off some usages of struct blk_dax_ctl on the way to its eventual removal. Suggested-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
