[llvm] [SPIRV] Fix sanitizer-x86_64-linux-android/8085 (PR #135189)

[Steven Perron via llvm-commits]

https://github.com/s-perron created https://github.com/llvm/llvm-project/pull/135189

The build failed because the cases covered all possibilities, so the
default was not needed. I have removed the default case, and placed the
llvm_unreachable after the switch.
