tests: Put seeker into extended listen when deferred PD is expected

Not doing so may result in a deferred PD flow failure (currently the
hwsim tests succeeded because seeker never stopped find, spending enough
time listening, so the follow-on PD would succeed).

Fix this by calling p2p_ext_listen when the seeker receives a deferred
PD failure event. Cancel extended listening when PD is done and also
stop find when seek is done.
