The cxl_test machinery builds modified versions of the modules in
drivers/cxl/ and intercepts some of their calls to allow cxl_test to
inject mock CXL topologies for test.
However, if cxl_test attempts the same with production modules,
fireworks ensue as Luis discovered [1]. Prevent that scenario by
arranging for cxl_test to check for a "watermark" symbol in each of the
modules it expects to be modified before the test can run. This turns
undefined runtime behavior or crashes into a safer failure to load the
cxl_test module.
