Herbert Xu bdecd22821 crypto: tcrypt - Abort and only log if there is an error 
The info printed is a complete waste of space when there is no error
since it doesn't tell us anything that we don't already know.  If there
is an error, we can also be more verbose.

In case that there is an error, this patch also aborts the test and
returns the error to the caller.  In future this will be used to
algorithms at registration time.
