Input: gpio_keys_polled - always use gpiod_get_value_cansleep
It does not matter if given GPIO may sleep or not when reading state,
polling is always done in a non-atomic context, so we should always
be able to simply use gpiod_get_value_cansleep().
Also let's note in the logs when we fail to read gpio state.
