Fix processing of channel list update events

Browse Source 
Commit 6bf731e8ce broke handling of
EVENT_CHANNEL_LIST_CHANGED by introducing a cached copy of the driver
channel list that does not get updated even if driver changes its list.
Fix this by synchronizing the cacched wpa_s->hw.modes information
whenever EVENT_CHANNEL_LIST_CHANGED is processed. This fixes P2P channel
list updates based on regulatory domain hints that may trigger driver to
change its supported channel list.
