mac80211: cancel the connection monitor timers/work

In "mac80211: monitor the connection" I forgot to
add code to cancel the new timers & work when the
interface is brought down, which isn't a problem
if you just bring it down, but _is_ a problem when
you destroy the interface. Correct this lapse.
