stable inclusion from stable-v5.10.110 commit ec1d372974ec82a2a15ebdce3df71af308ec8cb8 bugzilla: https://gitee.com/openeuler/kernel/issues/I574AL
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 66eae850333d639fc278d6f915c6fc01499ea893 ]
The function crypto_authenc_decrypt_tail discards its flags argument and always relies on the flags from the original request when starting its sub-request.
This is clearly wrong as it may cause the SLEEPABLE flag to be set when it shouldn't.
