Potential NULL pointer deference in drm/amdgpu

Hi All:
The function to_amdgpu_fence() could return NULL, but callers
in this file does not check the return value but directly dereference it,
which seems potentially unsafe.
Such callers include amdgpu_fence_get_timeline_name(),
amdgpu_fence_enable_signaling() and amdgpu_fence_free().

Kind Regards,
