  [AMDGPU] Fix dynamic LDS consistency check in setDynLDSAlign (#225825)

5bf967cb132b ("[RFC][AMDGPU] Add BARRIER address space") changed the
absolute-address check in `setDynLDSAlign` to read the dynamic LDS
global being lowered (`GV`) instead of the kernel's representative
`llvm.amdgcn.<kernel>.dynlds` variable (`Dyn`).

`amdgpu-lower-module-lds` attaches `!absolute_symbol` only to the
representative; uses of the original dynamic LDS global inside the
kernel are left in place and never carry that metadata. As a result, a
kernel that accesses dynamic LDS both directly and through a non-inlined
callee now aborts with "Inconsistent metadata on dynamic LDS variable".
