P2P: Advertize cross connection to WLAN AP on a non-P2P interface

P2P: Advertize cross connection to WLAN AP on a non-P2P interface

Commit 1c2aa04c96626f5b000d167bb5274a8c39b7dac2 ('P2P: Do not add P2P
IEs on P2P disabled interface') removed the P2P IEs from association on
non-P2P interface. However, an AP functioning as a P2P manager needs the
cross connection capability of the station (P2P Device). This needs to
be done to meet the P2P specification requirements even if the station
interface has p2p_disabled=1 in case P2P in general is enabled.
