[Beignet] [PATCH v2] Change the order of the code

[Xiuli Pan]

From: xiuli pan <xiuli.pan at intel.com>

Fix the 66K problem in the OpenCV testing.
The bug was casued by the incorrect order
of the code, it will result the beignet to
calculate the whole localsize of the kernel
file. Now the OpenCV test can pass.
