Use function attributes to catch misuse of GPU memory
at compile time.

v2 - remove test case where invalid pointer was being passed.
     The test is now caught at compile time, making a runtime test
     no longer necessary.

Stephen Hemminger (2):
  test-gpudev: avoid use-after-free and free-non-heap warnings
  gpudev: add malloc annotations to rte_gpu_mem_alloc

There is a build error due to referencing experimental symbol in annotation.
