[PATCH] ntfs: Fix validity check for file name attribute

I was just scanning through some older vulnerabilities and came across 
CVE-2018-12929, CVE-2018-12930, and CVE-2018-12931, which are all still open 
according to linuxkernelcves.com (originally reported against 4.15 [1]). I 
looked into the commits in fs/ntfs/ from 4.15 onwards to see if they were just 
missed, but I can't spot anything there. RedHat claims to have them fixed in 
one of their kernels [2].

Which makes me wonder if the issue fixed here is a duplicate of the any of the 
above. Is there a reason I can't find any patches for the original issue in 
tree, like the issue only introduced in a custom patchset that Ubuntu/RedHat 
were using? Is this thing worth it's own CVE if it's no duplicate?
