blk-integrity: register sysfs attributes on struct device

Browse source 
The "integrity" kobject only acted as a holder for static sysfs entries.
It also was embedded into struct gendisk without managing it, violating
assumptions of the driver core.

Instead register the sysfs entries directly onto the struct device.

Also drop the now unused member integrity_kobj from struct gendisk.
