In preparation for qemu maybe actually supporting variable refcount
widths in the far future, drop the hardcoded REFCOUNT_SHIFT and instead
use the value as given by the image.
Also, the qcow2 documentation gave the width of a refcount block entry
as sizeof(uint16_t), which is wrong for any refcount order other than 4.
Fix that.
This is a follow-up to my "[PATCH v5 00/11] qcow2: Fix image repairing"
series and therefore depends on it.
