md: move allocation of ->queue from mddev_find to md_probe
It is more balanced to just do simple initialisation in mddev_find,
which allocates and links a new md device, and leave all the
more sophisticated allocation to md_probe (which calls mddev_find).
md_probe already allocated the gendisk. It should allocate the
queue too.
