gpio: cdev: Don't check struct gpio_chip in gpio_chrdev_open()
It's harmless even if: chrdev_open() and cdev_device_del() run at the
same time, and gpio_chrdev_open() gets called after the underlying GPIO
chip has gone. The subsequent file operations check the availability
of struct gpio_chip anyway.
Don't check struct gpio_chip in gpio_chrdev_open().
