The invalid set/get tests do not serve the purpose of detecting whether
or not invalid parameters are indeed detect 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.
