Just as for external interrupts and I/O interrupts, we need to
initialize mchk_index during cpu reset.

Trying a device_add with a ccw device under tcg currently insta-crashes
qemu. Probably nobody ever tried the crw machine check support that I
hacked in...
Needs more work to avoid a guest kernel panic next; but let's pick the
low-hanging fruit first.
