qed: Fix consistency check on 32-bit hosts
The qed_bytes_to_clusters() function is normally used with size_t
lengths. Consistency check used it with file size length and therefore
failed on 32-bit hosts when the image file is 4 GB or more.
Make qed_bytes_to_clusters() explicitly 64-bit and update consistency
check to keep 64-bit cluster counts.
