Allow people to run `raidstart -aq` and not have raidtools bitch when 
it tries to start devices that are already started.  This allows us to 
simplify raidstarting at boot up.  If the user has all their devices 
autostart by the kernel, running `raidstart -a` would display a bunch 
of ugly warnings about the devices already being started.  Now we can 
just run `raidstart -aq` and let raidtools figure out whether it needs 
to start any of the devices or not.

Note that this patch isn't exactly "clean", it's a shortcut approach 
to keep patch size/maintenance down to a minimal.
