syzbot, using KMSAN, has reported an uninit-value access in
hwsim_cloned_frame_received_nl(). This is happening because frame_data_len

frame's header.
Fix this by bailing out in case frame_data_len is 0.
This really seems quite pointless - you should bail out if the frame is
too short for what we need to do, not just when it's 0.
