gpiolib: Optimize gpiochip_remove() when check for requested line
Here are the following optimizations have been done:
- break the loop after first found requested line
- due to above, drop redundant boolean variable
- replace open coded variant of gpiochip_is_requested()
- due to above, drop redundant pointer to struct gpio_desc
- use 'unsigned int' instead of 'unsigned' for loop counter
Note, pointer to struct gpio_chip followed by pointer to struct gpio_device
is still valid, back link is not.
