[llvm] AMDGPU: Fix using unaligned vgprs in mimg error test (PR #157001)

[Matt Arsenault via llvm-commits]

https://github.com/arsenm created https://github.com/llvm/llvm-project/pull/157001

These instructions really have 2 errors, from the unsupported
image base instruction plus the unaligned vgpr usage. This
test intends to test the base instruction error, so fix the
secondary error to avoid changing the diagnostic in a future
patch.
