LOG: Remove unused variable to fix '[AMDGPU] modify named barrier builtins and intrinsics (#114550)'

https://github.com/llvm/llvm-project/pull/114550 caused a buildbot breakage (https://lab.llvm.org/buildbot/#/builders/66/builds/5853) because of an unused variable. This patch attempts to fix forward:

/home/b/sanitizer-x86_64-linux/build/llvm-project/llvm/lib/Target/AMDGPU/AMDGPUMachineFunction.cpp:106:24: error: variable 'TTy' set but not used [-Werror,-Wunused-but-set-variable]
106 |     if (TargetExtType *TTy = AMDGPU::isNamedBarrier(GV)) {
    |                        ^
