P2P: Do not perform P2P GO CS in some cases

Browse source 
A P2P GO channel switch should not be triggered in all cases that
require channel list update. Specifically, a P2P GO CS should not
be triggered in case that the P2P GO state changed or in case that
that the P2P GO has just completed a CS.

To fix this, add reason code to wpas_p2p_channel_list_update() and
trigger CS flow only for the relevant cases.
