xfrm: optimise the use of walk list header in xfrm_policy/state_walk
The walk from input is the list header, and marked as dead, and will be skipped in loop. list_first_entry() can be used to return the true usable value from walk if walk is not empty Signed-off-by: Li RongQing <roy.qing.li@gmail.com> Acked-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
