[PATCH 01/17] tests: wait for radio work to start after DPP_LISTEN command

[Johannes Berg]

From: Johannes Berg <johannes.berg at intel.com>

Since DPP listen is a radio work, it doesn't start immediately and
then we can end up missing whatever happens next in the test. Wait
for the radio work to start before continuing the test.
