From: Ilan Peer <ilan.peer@xxxxxxxxx>
When processing the NL80211_CMD_PROBE_CLIENT command, the
nl80211 layer in the kernel sends a response containing the
cookie associated with the client probe request. This response
is not handled by driver_nl80211 when sending the command,
and is mistakenly handled as an asynchronous event.
Fix this by reading the response as part of the sending the
command flow.
