P2P: Set CTWindow only for P2P GO

CTWindow was set for all AP interfaces if the driver supports it and
this parameter is set in wpa_supplicant configuration. This results in
failing to start an AP that is not a P2P GO as this setting is rejected
by the driver.

Fix that by setting the CTWindow only for P2P GO interface.
