platform/x86: dell-privacy: Remove usage of wmi_has_guid()

The WMI driver core already takes care that the WMI driver is
only bound to WMI devices with a matching GUID.

Remove the unnecessary call to wmi_has_guid(), which will always
be true when the driver probes.

Tested on a Dell Inspiron 3505.
