drm/amd/pm: fix missing device_attr cleanup in amdgpu_pm_sysfs_init()

JIRA: https://issues.redhat.com/browse/RHEL-81536
Conflicts:
       drivers/gpu/drm/amd/pm/amdgpu_pm.c -
amdgpu_dpm_is_temp_metrics_supported() does not exist in RHEL-9,
so the second part of the stanza was dropped entirely

commit 37e3567
Author: Yang Wang <kevinyang.wang@amd.com>

Use the correct label to complete all cleanup work.
