[NET]: Move the filter releasing into a separate call
This is done merely as a preparation for the fix. The sk_filter_uncharge() unaccounts the filter memory and calls the sk_filter_release(), which in turn decrements the refcount anf frees the filter. The latter function will be required separately. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
