From: Pan Bian <bianpan2016@xxxxxxx> Function radeon_fence_emit() returns -ENOMEM if there is no enough memory. And in this case, function radeon_ring_unlock_undo() rather than function radeon_ring_unlock_commit() should be called. However, in function radeon_test_create_and_emit_fence(), the return value of radeon_fence_emit() is ignored. This patch adds the check.
