  exfat: add blank line after declarations (2026-02-12 21:21:51 +0900)

----------------------------------------------------------------
Description for this pull request:
 - Improve error code handling and four cleanups.
 - Reduce unnecessary valid_size extension during mmap write to avoid
   over-extending writes.
 - Optimize consecutive FAT entry reads by caching buffer heads in
   __exfat_ent_get to significantly reduce sb_bread() calls.
 - Add multi-cluster (contiguous cluster) support to
   exfat_get_cluster() and exfat_map_cluster() for better sequential read
   performance, especially on small cluster sizes.
