This solved a problem where 'vinum resetconfig' only reset half
the drives.

Change the super device. We now have three super devices:
1. The normal superdevice used by vinum(8).
2. The superdevice used by vinum(8) when compiled with debug support.
3. The superdevice used by the daemon.
This method allows vinum(8) to determine debug mismatches. Also check
correctly for the device type. The old code did not check all bits of
the minor number.
