[llvm] [AArch64] Fixup possibly unused variable warning after #207199 (PR #209418)

[Sander de Smalen via llvm-commits]

https://github.com/sdesmalen-arm created https://github.com/llvm/llvm-project/pull/209418

Using [[maybe_unused]] as the variable is only used in asserts which results in a diagnostic for no-assert builds.
