Enrico Weigelt, metux IT consult 90cd5c38ee randr: skip payload assembly in ProcRRGetScreenInfo() no data to send 
If there's no data to send, the whole reply payload can be skipped entirely.
This can also ease the whole code flow, and we don't need to rely on the
individual copy loops never trying to dereference a NULL pointer.
(what the analyzer can't proof). Also scoping several some variables that
are only used when there actually is data to send.
