igt/gem_eio: inflight wedged requires long plugging
As our hangcheck may exceed 10s to declare the device wedged, we need to
hold the plugging fence indefinitely. This makes using vgem as our input
fence unusable, so resort to using sw_sync. At the same time, we can
then check that the async result is also -EIO.
