[lld] [lld] Fix -Wunused-result in e44068cc129912c88dcdeae0d1b5dc5937eb1059 (PR #213296)

[Aiden Grossman via llvm-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/213296

These variables are only used in an assertion, so mark them maybe unused to avoid warnings in release builds.

Fixes https://lab.llvm.org/buildbot/#/builders/228/builds/6605.
