cogl: Revert "build: Remove unused variable"

Having ctx here produces a warning on GLES. However it's needed for Big
GL as we have at the top of the file:

 #ifdef HAVE_COGL_GL
 #define glClientActiveTexture ctx->drv.pf_glClientActiveTexture
 #endif

This reverts commit 27a3a2056a245aca64b8e3a7d82b7976c13e897a.
