gpiolib: check descriptors validity before use
Some functions dereferenced their GPIO descriptor argument without
checking its validity first, potentially leading to an oops when given
an invalid argument.
This patch also makes gpio_get_value() more resilient when given an
invalid GPIO, returning 0 instead of silently crashing.
