orinoco: convert scanning to cfg80211
This removes the custom scan cache used by orinoco.
We also have to avoid calling cfg80211_scan_done from the hard
interrupt, so we offload the entirety of scan processing to a workqueue.
This may behave strangely if you start scanning just prior to
suspending...
