[igt-dev] [PATCH i-g-t v2] i915/gem_exec_params: Cross-check getparam against engine execution

[Nirmoy Das <nirmoy.das@intel.com>]

From: Chris Wilson <chris.p.wilson@intel.com>

Do not just skip the test if getparam for bsd, blt, vebox passes.
Be more robust and compare result of getparam with a engine execution
which should give more test coverage.

v2: improve commit message and keep RUN_FAIL()(Kamil)
