The final check in this test case was issuing a new P2P_FIND command
immediately after the P2P_SERVICE_DEL command on the peer. It looked
like it was possible for the scan timing to go in a sequence that made
the new P2P_FIND operation eventually accept a cfg80211 BSS entry from
the very end of the previous P2P_FIND. This resulted in unexpected
P2P-DEVICE-FOUND event even though there was no new Probe Response frame
from the peer at that point in time.
Make this less likely to show unrelated failures by waiting a bit before
starting a new P2P_FIND operation after having changes peer
configuration.
