[PATCH] nl80211: Don't call linux_iface_up() for a dedicated P2P Device

[Ilan Peer]

As a dedicated P2P Device interface does not have a network
interface associated with it, trying to call linux_iface_up()
on it would always fail so this call can be skipped for
such an interface.

Getting interface nlmode can be done only after bss->wdev_id is
set, so move this call to wpa_driver_nl80211_finish_drv_init(),
and do it only in case the nlmode != NL80211_IFTYPE_P2P_DEVICE.
