Change 162045 by zec at zec_tpx32 on 2009/05/13 23:31:15

	if_free_internal() is called with ifp->if_vnet already set to
	NULL, so instead of fetching the vnet context from ifp->if_vnet,
	resort to curvnet instead.
	
	This unbreaks ifconfig destroy operations on cloning ifnets
	with options VIMAGE builds.
