[llvm] [llvm] remove llvm:: qualification from appendLoopsToWorklist extern template instantiations (PR #143555)

[Andrew Rogers via llvm-commits]

https://github.com/andrurogerz created https://github.com/llvm/llvm-project/pull/143555

## Purpose
Fix a build break introduced by #143413. This was a copy+paste error where the `llvm::` qualifier was left on the template instantiation declarations that were added. This causes a compile error with the version of the compiler used by the mlir-nvidia-gcc7 build. 
```

     ArrayRef<Loop *> &Loops, SmallPriorityWorklist<Loop *, 4> &Worklist);
                                                                        ^
