af_alg_test aes check writes only "info:" lines, but never errors.

I never compiled kernel, just using apt-get upgrade, so until the next armbian 
release with 4.4.2 kernel i can't try.

BTW i've forgot something: the errors with decryption only happens with big 
files (hundreds of mbytes), but not with small few kbyte files. Which file 
decrpyted wrongly and which is OK seems to always the same.

The errors are in ~10-~40 byte blocks, usually look like this: a block of 
errors, then few mbytes are perfect, then again a block with errors, again 
perfect, then error block again ...
