aoe: return real minor number for static minors

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.
