  [mlir][vector] Fix parser of vector.transfer_read (#133721)

This PR adds a check in the parser to prevent a crash when
vector.transfer_read fails to create minor identity permutation. map.
Fixes #132851

a.mlir

```
module {
  func.func @test_vector.transfer_read(%arg1: memref<?xindex>) -> vector<3x4xi32> {
    %c3_i32 = arith.constant 3 : i32
    %0 = vector.transfer_read %arg1[%c3_i32, %c3_i32], %c3_i32 : memref<?xindex>, vector<3x4xi32>
    return %0 : vector<3x4xi32>
  }
}
