drm/amdgpu: kfd_pre_reset outside req_full_gpu cause sriov hang
XGMI hive put kfd_pre_reset into amdgpu_device_lock_adev, but outside req_full_gpu of sriov. It would make sriov hang during reset. Signed-off-by: Wentao Lou <Wentao.Lou@amd.com> Reviewed-by: Shaoyun Liu <Shaoyun.Liu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
