gpio: improve error path in gpiolib ...
At several places the gpiolib will proceed to handle a GPIO
descriptor even if it's ->chip member is NULL and no gpiochip
is associated.
Fix this by checking that both the descriptor cookie *and*
the chip pointer are valid.
Also bail out earlier with more specific diagnostic messages
on missing operations for setting as input/output or debounce.
ChangeLog v1->v2:
- Also return -EIO on gpiod_set_debounce() with missing
operations in the vtable
- Fix indentations.
