[PATCH] crypto: atmel-tdes - use min3 to simplify sg_copy and crypt_start

[Thorsten Blum <thorsten.blum@linux.dev>]

Replace multiple min() and min_t() calls with min3() to simplify the
code. Using min3() instead of min_t() in atmel_tdes_crypt_start() is
safe since the values are all unsigned and compatible.
