  ntfs: open the index allocation before reading or writing an index
block (2026-11-08 12:43:07 +0900)

----------------------------------------------------------------
- Validate that $INDEX_ALLOCATION is open and non-resident before reading
  or writing index blocks, preventing NULL pointer dereferences when an
  earlier index operation has not opened it.

- Check that index allocation inodes are non-resident and child VCNs are
  non-negative and within bounds before directory lookup reads, preventing
  a deadlock when $INDEX_ALLOCATION is missing or damaged.

- Validate file names against the index entry's key length, preventing
  out-of-bounds reads when directory enumeration resumes using a copied
  key.

- Return -ENOENT for NTFS_IOC_LIST_STREAMS on deleted base files and fix
  unsigned underflow in its buffer bounds check, preventing out-of-bounds
  writes when the sizing and filling passes disagree.

- Use kfree() for the temporary runlist allocated with kmalloc() on merge
  failure, resolving the Coccinelle allocation/free mismatch warning.
