[IPSEC]: Remove bogus ref count in xfrm_secpath_reject
Constructs of the form xfrm_state_hold(x); foo(x); xfrm_state_put(x); tend to be broken because foo is either synchronous where this is totally unnecessary or if foo is asynchronous then the reference count is in the wrong spot. In the case of xfrm_secpath_reject, the function is synchronous and therefore we should just kill the reference count. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
