802: fix a possible race condition
(Resend with a better changelog)
garp_pdu_queue() should ways be called with this spin lock.
garp_uninit_applicant() only holds rtnl lock which is not
enough here. A possible race can happen as garp_pdu_rcv()
is called in BH context:
garp_pdu_rcv()
|->garp_pdu_parse_msg()
|->garp_pdu_parse_attr()
|-> garp_gid_event()
Found by code inspection.
