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.
