GValue – Don't cast G_VALUE_TYPE() argument to GValue*

Browse Source 
It's not possible to subclass GValue, and by always explicitly casting
here it is easy to write broken code (e.g. passing a GValue**) without
the compiler warning about that.

By not casting, the compiler will error out if anything but a GValue* is
passed here.
