[PATCH 17/25] [libx11] xcms/LRGB: Add a label for freeing property_return.

[Erkki Seppälä]

From: Ander Conselvan de Oliveira <ander.conselvan-de-oliveira at nokia.com>

The rest of the code uses goto's to free memory allocated later
and prevent memory leaks, but there were several paths were
property_return was free'd just before a goto.
