CVE-2023-53328

In the Linux kernel, the following vulnerability has been resolved:

fs/ntfs3: Enhance sanity check while generating attr_list

nicreateattrlist uses WARNON to catch error cases while generating attribute list, which only prints out stack trace and may not be enough. This repalces them with more proper error handling flow.
