[Piglit] [PATCH] fix CL_KERNEL_GLOBAL_WORK_SIZE bug.

[xionghu.luo at intel.com]

From: Luo <xionghu.luo at intel.com>

the option  CL_KERNEL_GLOBAL_WORK_SIZE for clGetKernelWorkGroupInfo
should call built in kernel or custom device according to the spec,
this patch calls the built in kernel to query the GLOBAL_WOR_SIZ.
