nl80211: add request id in scheduled scan event messages
For multi-scheduled scan support in subsequent patch a request id
will be added. This patch add this request id to the scheduled
scan event messages. For now the request id will always be zero.
With multi-scheduled scan its value will inform user-space to which
scan the event relates.
