@brief Get the next gpiochip handle without closing the previous one.
@param iter The gpiochip iterator object.
@return Pointer to the next open gpiochip handle or NULL if no more chips
are present in the system.
@note This function works just like ::gpiod_chip_iter_next but doesn't
close the most recently opened chip handle.
