Use v4l2_disable_ioctl() to disable the stateful encoder ioctls
VIDIOC_ENUM_FRAMEINTERVALS, VIDIOC_G_PARM, and VIDIOC_S_PARM for
the jpeg encoder device, to fix this v4l2-compliance test failure:

		fail: v4l2-test-formats.cpp(68): node->is_m2m && !(node->codec_mask & STATEFUL_ENCODER)
	test VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS: FAIL
		fail: v4l2-test-formats.cpp(1363): node->is_m2m && !is_stateful_enc
	test VIDIOC_G/S_PARM: FAIL
