Fix defects detected by Coverity Scan 2021.12.1: Unintentional integer overflow

Browse Source 
overflow_before_widen: Potentially overflowing expression this->d_fft_size * ninput_items[0UL] with type unsigned int (32 bits, unsigned) is evaluated using 32-bit arithmetic, and then used in a context that expects an expression of type uint64_t (64 bits, unsigned)
