  exfat: Add support for FS_IOC_{GET,SET}FSLABEL (2025-09-30 13:49:31 +0900)

----------------------------------------------------------------
Description for this pull request:
 - Add support for FS_IOC_{GET,SET}FSLABEL ioctl.
 - Two small clean-up patches.
 - Optimizes allocation bitmap loading time on large partitions
   with small cluster sizes.
 - Allow changes for discard, zero_size_dir, and errors options
   via remount.
 - Validate that the clusters used for the allocation bitmap are
   correctly marked as in-use during mount, preventing potential
   data corruption from reallocating the bitmap's own space.
 - Uses ratelimit to avoid too many error prints on I/O error path.
