[llvm] [MC] Fix HIP buildbot errors after 68472a3 (PR #141138)

[Jan Patrick Lehr via llvm-commits]

https://github.com/jplehr created https://github.com/llvm/llvm-project/pull/141138

This fixes the errors on our HIP-Kokkos buildbot after 68472a39a0fbf38f5da7bb4ebe43e2ca87ff8308.

I do not know if this is the actually right fix, but afaict it restores the behavior for AMDGPU before the mentioned patch.
