[Piglit] [PATCH v2] cl: Initialize errNo on invalid image type.

[Vinson Lee]

Fixes sometimes-uninitialized warning.

piglit-util-cl.c:1052:13: warning: variable 'errNo' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
        } else if (desc->image_type == CL_MEM_OBJECT_IMAGE3D) {
                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
piglit-util-cl.c:1062:28: note: uninitialized use occurs here
        if(!piglit_cl_check_error(errNo, CL_SUCCESS)) {
                                  ^~~~~
piglit-util-cl.c:1052:9: note: remove the 'if' if its condition is always true
        } else if (desc->image_type == CL_MEM_OBJECT_IMAGE3D) {
               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
piglit-util-cl.c:1040:14: note: initialize the variable 'errNo' to silence this warning
        cl_int errNo;
                    ^
                     = 0
