[clang] [NFC] Fix hasQualifier comment (PR #90485)

[Jorge Pinto Sousa via cfe-commits]

https://github.com/sousajo-cc created https://github.com/llvm/llvm-project/pull/90485

operator bool from NestedNameSpecifierLoc and
member function hasQualifier both do the same thing, returning true iff the private data member Qualifier is not nullptr, so clearly one of the comments is wrong, and in this case it is the second one.
