HID: sony: Don't use fw_version/hw_version for sysfs cleanup.
The DS4 dongle reports fw_version and hw_version as 0 when no actual
DS4 is connected to it. This prevents cleaning up sysfs nodes upon
device remove.
This patch decouples sysfs cleanup from the fw_version and hw_version
values by introducing boolean values.
