compiler-clang.h: Remove __cleanup -Wunused-variable workaround

Now that the minimum supported version of LLVM for building the kernel
has been raised to 17.0.1, the redefinition of __cleanup with
__maybe_unused added to it is unnecessary because the referenced LLVM
change is present in all supported LLVM versions. Drop it.
