https://github.com/llvm/llvm-project/pull/90201 made some fixes for gfx12 image_msaa_load waitcnt insertion. That fix might break in some situations for pre-gfx12 - this fixes that by explitly checking for VSAMPLE which always requires a s_wait_samplecnt and leaves the previous logic intact for non-gfx12.
