The dm tree is defintively the better place then.

Set max_integrity_segments with the other queue limits instead of updating it later. This also uncovered that the driver is trying to set the limit to UINT_MAX while max_integrity_segments is an unsigned short, so fix it up to use USHRT_MAX instead.
