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.
