Subject: [PATCH 2/2] xfrm: Fix installation of AH IPsec SAs

From: Tobias Brunner <tobias@...ongswan.org>

The SPI check introduced in ea9884b3acf3311c8a11db67bfab21773f6f82ba
was intended for IPComp SAs but actually prevented AH SAs from getting
installed (depending on the SPI).

Fixes: ea9884b3acf3 ("xfrm: check user specified spi for IPComp")
