Subject: drm/amd/amdgpu: skip locking delayed work if not initialized.
Git-commit: e78b3197dbf73fc0695dd019e388576d0a551830
Patch-mainline: v5.15-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

When init failed in early init stage, amdgpu_object has
not been initialized, so hasn't the ttm delayed queue functions.
