[Beignet] [PATCH] Add clGetKernelSubGroupInfoKHR to _cl_icd_dispatch table

[Rebecca N. Palmer]

ocl-icd >= 2.2.8 has this function in its table; as the lookup process
tries the dispatch table before the ICD's clGetExtensionFunctionAddress,
requesting a function that is in the ICD loader's table but off the end
of the ICD's table will return a garbage pointer.
