Subject: [PATCH 04/15] ipvs: Pass destination address family to ip_vs_trash_get_dest

From: Alex Gartrell <agartrell@...com>

Part of a series of diffs to tease out destination family from virtual
family.  This diff just adds a parameter to ip_vs_trash_get and then uses
it for comparison rather than svc->af.
