 Log Message:
 wg-userspace(8): Drop <4-byte UDP packets immediately.
 
 Same as the kernel already does.  Add an assertion into
 wg_receive_packets about this and a couple comments cross-referencing
 wg_overudp_cb and wg_receive_packets.
 
 And, while here, as a precaution in case the
 inpcb_register_overudp_cb mechanism ever breaks down or gets
 refactored, make wg_receive_packets drop <4-byte packets too -- this
 path should be hit only when handling handshake packets, so adding
 another predicted-not-taken branch here should cost essentially
 nothing.
