  -----------
  [AMDGPU] Fix LDS address correction in promoteConstantOffsetToImm for async stores (#180220)

`updateAsyncLDSAddress`, introduces by
https://github.com/llvm/llvm-project/pull/176816, previously only
handled async loads , where the LDS address is in the `vdst` operand.
Therefore Async stores produced a nullptr dereference since the LDS
address is in `vdata` for those instructions.
