[igt-dev] [PATCH i-g-t] i915/perf: Ensure i915.ko is loaded before requiring its procfs files

[Petri Latvala]

If for example i915_module_load is executed before this test, i915.ko
is not loaded and /proc/sys/dev/i915/perf_stream_paranoid naturally
does not exist. Ensure the module is loaded by briefly opening
DRIVER_INTEL.
