[PATCHv5 1/9] blk-mq: unconditional nr_integrity_segments

Always defining the field will make using it easier and less error prone
in future patches.

There shouldn't be any downside to this: the field fits in what would
otherwise be a 2-byte hole, so we're not saving space by conditionally
leaving it out.
