[INET]: Consolidate xxx_frag_create()
This one uses the xxx_frag_intern() and xxx_frag_alloc() routines, which are already consolidated, so remove them from protocol code (as promised). The ->constructor callback is used to init the rest of the frag queue and it is the same for netfilter and ipv6. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.
