[PATCH 12/12] block: move integrity information into queue_limits

[Martin K. Petersen]

Christoph,

> Move the integrity information into the queue limits so that it can be
> set atomically with other queue limits, and that the sysfs changes to
> the read_verify and write_generate flags are properly synchronized.
> This also allows to provide a more useful helper to stack the
> integrity fields, although it still is separate from the main stacking
> function as not all stackable devices want to inherit the integrity
> settings. Even with that it greatly simplifies the code in md and dm.
