rnull: fix geometry store check-then-act across lock scopes
750b5df 
The blocksize/rotational/capacity/irqmode stores check powered under one
Mutex acquisition, drop the guard, then update under a second acquisition.
A concurrent power-on can create the live disk from stale geometry in
between, leaving powered==true with config != live disk.

Hold one guard for the powered check and the field update.
