kdg2kfd_probe failed

[Oded Gabbay]

HI Sen,

Those messages are expected and you can ignore them.

In kernel 4.14 a couple of warning/error messages were added to
amdkfd. If you use the amdgpu driver you will not see them but because
you use radeon you are seeing them.
In kernel 4.15 we removed support of amdkfd from radeon, so once
fedora will upgrade to 4.15 (or later) you will again stop seeing
those messages.
