[mlir][Analysis] Guard data flow analysis from no block function

Foo analysis for testing the data flow analysis does not support the region without any block. Although that analysis is assumed to be used for testing purpose, it is generally better to be explicit about the scope the framework supports.

The original issue was reported here.
