Commit72daceb9a1("net: rfkill: gpio: Add default GPIO driver mappings for ACPI") removed possibility to request GPIO by table index for non-ACPI platforms without changing its users. As result "shutdown" GPIO request will fail if request for "reset" GPIO succeeded or "reset" will be requested instead of "shutdown" if "reset" wasn't defined. Fix it by making gpiod_lookup_table use con_id's instead of indexes.
