[Piglit] [PATCH] cl-api-compile-program: Initialize variable.

[Vinson Lee]

This patch silences Clang sometimes-uninitialized warnings.

compile-program.c:312:6: warning: variable 'kernel' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]
                if(!piglit_cl_check_error(errNo, CL_SUCCESS)) {
                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compile-program.c:332:18: note: uninitialized use occurs here
        clReleaseKernel(kernel);
                        ^~~~~~
compile-program.c:312:3: note: remove the 'if' if its condition is always false
                if(!piglit_cl_check_error(errNo, CL_SUCCESS)) {
                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compile-program.c:302:5: warning: variable 'kernel' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]

        cl_kernel kernel;
                        ^
                         = NULL
