  [-Wunsafe-buffer-usage] Fix a small bug recently found (#102953)

`QualType::isConstantArrayType()` checks canonical type. So a following
cast should be applied to canonical type as well:

```
if (Ty->isConstantArrayType())
  cast<ConstantArrayType>(Ty.getCanonicalType());  //  cast<ConstantArrayType>(Ty) is incorrect
```
