Gack. Clean bits don't mean a whole lot for RAID0, so perhaps
the error message here is a bit bogus..

should make it happier. The initializing of parity should trivially
succeed (as there is no parity) and after that the kernel shouldn't complain
about the RAID set not being clean...
Please let me know if the above doesn't fix things, as if it doesn't, I'll
need to do some digging...
