Yuezhang Mo a5324b3a48 exfat: fix the infinite loop in __exfat_free_cluster() ... In __exfat_free_cluster(), the cluster chain is traversed until the EOF cluster. If the cluster chain includes a loop due to file system corruption, the EOF cluster cannot be traversed, resulting in an infinite loop. This commit uses the total number of clusters to prevent this infinite loop.
