  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.

Thank you for your contribution, it has been applied to my local
review-ilpo branch. Note it will show up in the public
platform-drivers-x86/review-ilpo branch only once I've pushed my
local branch there, which might take a while.
