steps to reproduceļ¼
`mlir-opt temp.mlir -test-transform-dialect-erase-schedule
`
test case:
```mlir

%transform_copy = transform.structured.match ops{["linalg.copy"]} in %arg0 : (!transform.any_op) -> !transform.any_op
transform.nvgpu.rewrite_copy_as_tma %transform_copy : (!transform.any_op) -> ()
transform.yield
}
}
```
crash trace:
```
