description:
Make DRM_IOCTL_GET_CLIENT work except for pid and uid.

The pid and uid don't make sense because the client is associated
with a file descriptor, which may be held by multiple processes, and
even if only one holds it (which is probably the only sensible state
of affairs), there's no index.
