API ieee802_1x_mka_decode_dist_sak_body wrongly puts
participant->to_use_sak to TRUE, if Distributed SAK Parameter Set of
length 0 is received; In MACsec PSK mode, this stale incorrect value can
create problems, while re-establishing CA. In MACsec PSK mode, CA goes
down if interface goes down and ideally we should be able to re-establish
the CA once interface comes up.
