drm/amdkfd: fix clock counter retrieval for node without GPU
[ Upstream commit
1cf6cc74bbeb85bb87c3ca3f3df97a283c3aa737 ]
Currently if a user requests clock counters for a node without a GPU
resource we will always return EINVAL.
Instead if no GPU resource is attached, fill the gpu_clock_counter
argument with zeroes so that we may proceed and return valid CPU
counters.
