parallels: collect bitmap of used clusters at open
If the operation is failed, we need to check image consistency if the
problem is not about memory allocation.
Bitmap adjustments in allocate_cluster are not performed yet.
They worth to be separate. This was proven useful during debug of this
series. Kept as is for future bissecting.
It should be specifically noted that used bitmap must be recalculated
if data_off has been fixed during image consistency check.
