Avoid injecting hangs in to the i915->kernel_context in case the GPU reset leaves corruption in the context image in its wake (leading to continual failures and system hangs after the selftests are ostensibly complete). Use a sacrificial kernel_context instead. v2: Closing a context is tricky; export a function (for selftests) from i915_gem_context.c to get it right.
