[Piglit] [PATCH] cl-api-get-platform-ids: Initialize variable.

[Vinson Lee]

Fix clang sometimes-uninitialized warning.

get-platform-ids.c:62:5: warning: variable 'platforms' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]
        if(!piglit_cl_check_error(errNo, CL_SUCCESS)) {
           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
get-platform-ids.c:93:30: note: uninitialized use occurs here
        errNo = clGetPlatformIDs(0, platforms, NULL);
                                    ^~~~~~~~~
get-platform-ids.c:62:2: note: remove the 'if' if its condition is always false
        if(!piglit_cl_check_error(errNo, CL_SUCCESS)) {
        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
get-platform-ids.c:56:27: note: initialize the variable 'platforms' to silence this warning
        cl_platform_id* platforms;
                                 ^
                                  = NULL
