dm vdo: rework processing of loaded refcount byte arrays
Clear provisional refcount values and count free/allocated blocks in
one integrated loop. Process 8 aligned bytes at a time instead of
every byte individually.
On an Intel i7-11850H this reduces the CPU time needed to process a
loaded refcount block by a factor of about 5-6. On a large system the
refcount loading may be the largest factor in device startup time.
