  -----------
  [mlir][vector] Fix error handling in VectorizationState::initState

This function used to create new ops even if the vectorization failed. Those ops were then folded away. This caused a failure of the GreedyPatternRewriter, which no longer terminated (each time the IR is modified => one more iteration).
