[Beignet] [Patch v2 1/2] [OCL20] fix compiler_generic_atomic utest bug.

[xionghu.luo at intel.com]

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

should use opencl 2.0 API to test generic atomic, the atomic_fetch_add
will return the old value of the source pointer, so should move the src
data to dst with another instruction.
