DPP: Remove dpp-listen radio work when stopping

Browse source 
The radio work starting may be delayed. If the DPP listen operation is
stopped before the radio work starts, the pending dpp-listen radio work
won't get cleaned up, which might lead to failing to start the next DPP
listen operation.

Issue scenario: DPP start -> dpp-listen radio work added but not started
-> DPP stop, pending radio work not cleaned up -> radio work start ->
trying to start DPP but failing because a dpp-listen work already
exists.

This commit removes the potential pending dpp-listen radio
work when DPP stops.
