The value returned by the static minor device number number allocator is the real minor number, so it must be multiplied by the supported number of partitions per aoedev.
Without this fix the support for systems without udev is incomplete, and the few users of aoe on such systems will have surprising results when device nodes names do not match the AoE target.
