This won't work. the kfd_debugfs directory is system-wide. So you cannot
have a per-GPU criteria for creating it. You may have one GPU that
probes successfully, another that fails. You still need the debugfs. If
you have multiple GPUs probing successfully, you only want to create the
debugfs node
v1:
the kfd debugfs node is rely on kgd2kfd probe success,
if not, the kfd_debugfs should not be created,
and the node of "hang_hws" should be disabled on vf mode.
v2:
also move kfd_debugfs_fini() into kgd2kfd_device_exit() function.
1. move kfd_debugfs_init() function into kgd2kfd_probe()
