glx: DoQueryContext(): use fixed size array instead of variable length 

Our array here really is fixed, but it's size is determined by a variable
(that's assigned a fix values), unncessarily making it a VLA (even making
it const doesn't change that), so giving false alarms when compiling w/
-Wvla or -Werror=vla.

Replacing the variable by #define trivially fixes this.
