nl80211: Clear bss->freq on station mode disconnection

Browse source 
This fixes some issues where bss->freq could have been used to replace
the current operating channel when sending out a management frame.
bss->freq has not been consistently used to track the current operating
channel in station mode, so it should not be trusted for this type of
uses. Clearing it makes this a bit more robust by at least avoiding the
cases of information from past association being used.
