[PATCH 1/2] crypto: sunxi-ss-cipher: promote variables to match types in min3() calls

[Andre Przywara]

The min3() macro expects all arguments to be of the same type (or
size at least).
Change the type of some local variables in sun4i-ss-cipher.c to
size_t to match the type used in some generic structures we
compare against.
That shouldn't change anything for 32-bit (as size_t is unsigned int
there anyway), but allows compilation for 64-bit architectures.
