block: ensure correct integrity capability propagation in stacked devices

queue_limits_stack_integrity() incorrectly sets
BLK_INTEGRITY_DEVICE_CAPABLE for a DM device even when none of its
underlying devices support integrity. This happens because the flag is
inherited unconditionally. Ensure that integrity capabilities are
correctly propagated only when the underlying devices actually support
integrity.
