Stop abusing the rcvif pointer to pass wireless nodes down to the
driver start routines. Instead add & use a pointer in the pkthdr
since we don't want the overhead of using a mbuf_tags(9).
claudio@ pointed out that other subsystems might want to use this
pointer too, so here's a new cookie!
ok claudio@, mikeb@, deraadt@
