winex11.drv: xrandr1.2 don't assume CRTC 0 is active

[Patrick Rudolph]

On my PC there are two CRTCs. CRTC 0 is disabled by default and CRTC 1 
is active by default.
With this patch wine does not fail to init/get/set the display-mode 
with more than one CRTC connected to the current screen and CRTC 0 
disabled.
I added a loop to cycle through every CRTC and test if its active. If 
so it is used instead of CRTC 0.
