[PATCH net-next-2.6] xfrm: remove unneeded method typedef declaration in net/xfrm.h.

Hi,

 The patch removes unneeded method typedef declaration
(icv_update_fn_t ) in net/xfrm.h.
(I am sending the same patch again as my former mail was  rejected by
the vger server, now I believe it will be fine).

icv_update_fn_t was used in the past, for example in xfrm_algo.c (as a
parameter to skb_icv_walk() method), but it is no longer used
anywhere.

This patch removes it and the two struct declarations which appear in
its prototype

 (struct hash_desc and struct scatterlist)


Regards,
Rami Rosen
