zbd: fixup ->zone_size_log2 if zone size is not power of 2

Code like this doesn't work if log2 is 0xffffffff.

if (f->zbd_info->zone_size_log2 > 0)
                zone_idx = offset >> f->zbd_info->zone_size_log2;
        else
                zone_idx = offset / f->zbd_info->zone_size;

Other than that everything else works!
