Ricardo Ribalda Delgado 119bf9470b gpiolib: Free the last requested descriptor ...

commit 19a4fbffc9 upstream.

The current code only frees N-1 gpios if an error occurs during
gpiod_set_transitory, gpiod_direction_output or gpiod_direction_input.
Leading to gpios that cannot be used by userspace nor other drivers.
