smatch does not track initialised values as well as gcc, and this triggers many warnings by smatch not presented by gcc. Silence smatch by initialising the error values to -ENODEV, which we use to denote internal errors. (If we see a selftest fail with a silent -ENODEV, we know smatch was right!) v2: smatch was right about igt_create_vma(), it may unlikely fail on the first object allocation which we want to be loud about.
