Revert "crypto: talitos - convert to use be16_add_cpu()"

This reverts commit 7291a932c6e27d9768e374e9d648086636daf61c.

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.
