igt_allow_hang() checks that the GPU can be reset before allowing the
test to cause a GPU hang (which would need the reset to recover).
However, our checking for allowing a hang depends on i915.reset which we
later restore. Do that restoration before the check so that this test is
not affected by earlier fails.
