[Qemu-devel] [PATCH v4 3/3] acpi-test: issue errors instead of warnings when possible

[Marcel Apfelbaum <marcel.a@redhat.com>]

If the expected (offline) acpi tables loaded correctly,
it is safe to assume the iasl installation is OK and
issue an error if the actual tables failed to load.

Signed-off-by: Marcel Apfelbaum <marcel.a@redhat.com>
---
v3->v4:
    - Do not issue error on tables sync issues to not break git bisect

v2->v3:
    Addressed Michael S. Tsirkin's comments:
    - got rid of a not needed if statement
