md-raid0: conditional mddev->queue access to suit dm-raid This patch is a prerequisite for dm-raid "raid0" support to allow dm-raid to access the MD RAID0 personality doing unconditional accesses to mddev->queue, which is NULL in case of dm-raid stacked on top of MD. Most of the conditional mddev->queue accesses made it to upstream but this missing one, which prohibits md raid0 to set disk stack limits (being done in dm core in case of md underneath dm).
