src/acpi/device: Early return in _ON if device already enabled
If the device has enabled `use_gpio_for_status`, then call the `_STA`
method in `_ON` to determine if the device is already enabled. If it is
already enabled, return early to skip re-enabling the device and
performing the associated sleep.
This change is necessary since the Linux kernel does not call `_STA`
before calling `_ON`.
