exfat: fix overflow in cluster-to-dentry conversion
The cluster-to-dentry calculation is performed as u32 and may overflow
and wrap around on large volumes. This can result in an incorrect
max_dentries value, causing readdir to stop early and omit directory
entries.
Cast nr_clusters to u64 before shifting to avoid the overflow.
