drm/amd/pm: fix a potential gpu_metrics_table memory leak

Browse source 
[ Upstream commit aa464957f7 ]

Memory is allocated for gpu_metrics_table in renoir_init_smc_tables(),
but not freed in int smu_v12_0_fini_smc_tables(). Free it!

Fixes: 95868b8576 ("drm/amd/powerplay: add Renoir support for gpu metrics export")
