gpio: Change to call flock with void type conversion

In the API "gpio_modern_set_direction_xor_edge_mode",
After flock fd and set edge mode or direction, unlock fd.
This API doesn't use the return value of unlock and use
the return of setting edge mode or direction.
So, in calling fd unlock, change to call with void type conversion.
