Previously, we used __builtin_mul_overflow() to check for overflow in the multiplication operation in the calloc() function. However, older compiler versions don't support this built-in. This patch changes the overflow checking mechanism to make it work on any compiler version by using a division method to check for overflow. No functional change intended. While in there, remove the unused variable `void *orig`.
