Bug#675407: xserver-xorg-video-openchrome: openchrome relink against new xserver results in null pointer dereference

[Leon Winter <winter-debian-675407@bfw-online.de>]

Hi,

the proposed patch does not work since the dereference already happens a 
few lines before the located position in ViaDoubleCheckCLE266Revision(). 
I moved the initialization before the call and can confirm it is working.

Best regards,
Leon Winter
