[changqing.li at windriver.com]

From: Changqing Li <changqing.li at windriver.com>

When enable DEBUG_BUILD, cogl compile failed with error:

| ../../cogl-1.22.2/cogl/driver/gl/gles/cogl-driver-gles.c:217:17: error: 'gltype' may be used uninitialized in this function [-Werror=maybe-uninitialized]
|      *out_gltype = gltype;
|      ~~~~~~~~~~~~^~~~~~~~
| ../../cogl-1.22.2/cogl/driver/gl/gles/cogl-driver-gles.c:213:22: error: 'glintformat' may be used uninitialized in this function [-Werror=maybe-uninitialized]
|      *out_glintformat = glintformat;
|      ~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~

it can handle correctly, so fix with -Wnoerror
