  ntfs: Use return instead of goto in ntfs_mapping_pairs_decompress()
(2026-04-30 07:05:48 +0900)

----------------------------------------------------------------
Description for this pull request:
 - Fix a NULL pointer dereference in ntfs_index_walk_down() by validating
   index block allocation.
 - Fix a memory leak of the symlink target string in
   ntfs_reparse_set_wsl_symlink() during error paths.
 - Prevent VCN overflow and validate lowest_vcn in
   ntfs_mapping_pairs_decompress() to avoid runlist corruption.
 - Fix a page reference leak in ntfs_write_iomap_end_resident() when
   attribute search context allocation fails.
 - Fix an invalid PTR_ERR() usage on a valid folio pointer in
   __ntfs_bitmap_set_bits_in_run().
 - Correct directory link counting by dropping nlink only when the MFT
   record link count reaches zero for WIN32/DOS aliases.
 - Fix an uninitialized variable usage in ntfs_mapping_pairs_decompress()
   by returning an error pointer directly.
