[PATCH] ipsec: select CRYPTO_HASH for xfrm_algo

From: Arnd Bergmann
Date: Tue Jun 18 2019 - 03:20:36 EST

kernelci.org reports failed builds on arc because of what looks
like an old missed 'select' statement:

net/xfrm/xfrm_algo.o: In function `xfrm_probe_algs':
xfrm_algo.c:(.text+0x1e8): undefined reference to `crypto_has_ahash'

I don't see this in randconfig builds on other architectures, but
it's fairly clear we want to select the hash code for it, like we
do for all its other users.

Fixes: 17bc19702221 ("ipsec: Use skcipher and ahash when probing algorithms")
