[PATCH] md: use ffz instead of find_first_set to convert multiplier to shift
find_first_set doesn't find the least-significant bit on bigendian machines,
so it is really wrong to use it.
ffs is closer, but takes an 'int' and we have a 'unsigned long'. So use
ffz(~X) to convert a chunksize into a chunkshift.
