randr: no need to for local temp buffer in ProcRRQueryProviderProperty() 

The code can be much simpler by just using CopySwap32Write().
And we also don't need the callback in WriteSwappedDataToClient(),
just call the corresponding write function directly.

This also makes some analyzer warnings go away.
