[ 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.
Fixes: 92d95ba91772 ("crypto: authenc - Convert to new AEAD interface")
