    igt/gem_ctx_isolation: Reset a scratch context

    If we inject a reset into the target context, there is a risk that the
    register state is never saved back to memory. The exact interaction
    between reset, the context image and the precise timing of our execution
    are not well defined. Since we cannot ensure that the context image
    remains valid, force a context switch prior to the reset.
