[PATCH i-g-t v3 1/6] tests/core_hotunplug: Free mem allocated by igt_audio_driver_unload

[Janusz Krzysztofik]

Since we pass NULL to igt_audio_driver_unload(), realloc() it calls
allocates new memory for us.  Free it each time we no longer need it,
before dropping a pointer to it, to avoid memory leaking.
