[IPSEC]: Merge common code into xfrm_bundle_create
Half of the code in xfrm4_bundle_create and xfrm6_bundle_create are
common. This patch extracts that logic and puts it into
xfrm_bundle_create. The rest of it are then accessed through afinfo.
As a result this fixes the problem with inter-family transforms where
we treat every xfrm dst in the bundle as if it belongs to the top
family.
This patch also fixes a long-standing error-path bug where we may free
the xfrm states twice.
