Revert "crypto: talitos - convert to use be16_add_cpu()"
commit 69d9cd8c592f1abce820dbce7181bbbf6812cfbd upstream.
This reverts commit 7291a932c6
.
The conversion to be16_add_cpu() is incorrect in case cryptlen is
negative due to premature (i.e. before addition / subtraction)
implicit conversion of cryptlen (int -> u16) leading to sign loss.
