[clang] [HLSL] update StructuredBuffer subscript test for alwaysinline (PR #109023)

[Greg Roth via cfe-commits]

https://github.com/pow2clk created https://github.com/llvm/llvm-project/pull/109023

The Alwaysinline change made the mangled form of entry points get removed. The StructuredBuffer-subscript.hlsl test was introduced in the meantime depending on that version of the entry point. This revises it in the same way as RWBuffer-subscript

Follow up to #89282
