[INET]: Consolidate the xxx_frag_kill
Since now all the xxx_frag_kill functions now work with the generic inet_frag_queue data type, this can be moved into a common place. The xxx_unlink() code is moved as well. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
