crypto: talitos - Pass correct interrupt status to error handler
Since we ack early, the re-read interrupt status in talitos_error
may be already updated with a new value. Pass the error ISR value
directly in order to report and handle the error based on the correct
error status.
Also remove unused error tasklet.
