net: af_key: check encryption module availability consistency
[ Upstream commit 015c44d7bff3f44d569716117becd570c179ca32 ] Since the recent introduction supporting the SM3 and SM4 hash algos for IPsec, the kernel produces invalid pfkey acquire messages, when these encryption modules are disabled. This happens because the availability of the algos wasn't checked in all necessary functions. This patch adds these checks.
