GPU-DRM: Delete an unnecessary check before drm_property_unreference_blob()

Browse Source 
The drm_property_unreference_blob() function tests whether its argument
is NULL and then returns immediately.
Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
