[clang] [HLSL] Remove dead code in Type.cpp [NFC] (PR #146365)

[Steven Perron via cfe-commits]

https://github.com/s-perron created https://github.com/llvm/llvm-project/pull/146365

In a case statement for Type::HLSLInlineSpirv, the first statment
returns, and the remaining statement are never executed. This removes
the dead code.
