[PATCH i-g-t 2/9] tests/intel/perf_pmu: Remove trial unload

[Lucas De Marchi <lucas.demarchi@intel.com>]

Remove the trial module so there are no more users of
__igt_i915_driver_unload() and thus i915 can start sharing the xe logic.
Later when perf_pmu_unregister() is fixed in the kernel, a new check can
be added for trying to unbind the device while still having open events.
