[clang] [Clang][HLSL] Fix -Wunused-variable (PR #194374)

[Aiden Grossman via cfe-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/194374

Inline the variable definition into the assert given it is side effect
free and the variable name does not make the code much more clear.
