stable inclusion from stable-v5.10.120 commit ac8d5eb26c9edeb139af1e02e1d3743aa2e1fcd7 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5L6BR

--------------------------------
[ 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.
