Following logic from commit: 22f6592b23, GPIOHANDLE_REQUEST_OUTPUT should handle errors same way as GPIOHANDLE_REQUEST_INPUT does, or else the following error occurs:
gpio-mockup-chardev: gpio<gpiochip1> line<0> test flag<0x2> value<0>: No such file or directory
despite the real result of gpio_pin_test(), gpio_debugfs_get() and gpiotools_request_linehandle() functions.
