    drm/amd/pm: Fix a potential gpu_metrics_table memory leak
    
    [ Upstream commit 5afb76522a0af0513b6dc01f84128a73206b051b ]
    
    Memory is allocated for gpu_metrics_table in
    smu_v13_0_4_init_smc_tables(), but not freed in
    smu_v13_0_4_fini_smc_tables(). This may cause memory leaks, fix it.
