Fix local work size for conv kernel yxfb_yxio_b16 with fp16 (openvino…

…toolkit#11679)

convolution_gpu_yxfb_yxio_b16 for fp16 has hardcoded reqd_work_group_size
to (16, 1, 1). On devices where CL_DEVICE_MAX_WORK_GROUP_SIZE is 512
GetOptimalLocalWorkGroupSizes picks (16, 2, 1) for LWS.
That causes issues during clEnqueueNDRangeKernel since LWS doesn't match
with reqd_work_group_size in the kernel.
