Above issue may happens as follows:
ntfs_new_inode
  mi_init
    mi->mrec = kmalloc(sbi->record_size, GFP_NOFS); -->failed to allocate memory
      if (!mi->mrec)
        return -ENOMEM;
iput
  iput_final
    evict
      ntfs_evict_inode
        ni_write_inode
	  is_rec_inuse(ni->mi.mrec)-> As 'ni->mi.mrec' is NULL trigger NULL-ptr-deref

To solve above issue if new inode failed make inode bad before call 'iput()' in
'ntfs_new_inode()'.
