[flang-commits] [flang] [flang][OpenMP] Remove unnecessary check for extension clauses (PR #228878)

[Krzysztof Parzyszek via flang-commits]

https://github.com/kparzysz created https://github.com/llvm/llvm-project/pull/228878

Remove the check for extension clauses. These now do have descriptors, so the check guarding the descriptor retrieval is no longer necessary.
