    i915/gem_ctx_param: Remove kneecapping

    The invalid set/get tests do not serve the purpose of detecting whether
    or not invalid parameters are indeed detected correctly -- simply because
    the kernel is the arbiter of what is invalid and this test second
    guesses that and is wrong.

    The intent of this test was to ensure that we didn't include any holes
    in the parameter space that may have been used for nefarious undisclosed
    purposes, i.e. the maintainer's job backed up by reviewers.

    As proving no holes is impossible without fuzzing/exhaustive search and
    a whitelist, accept defeat and just check whether the very last
    parameter (which should be unused for a long, long time) is invalid.
