[Impact]
An allocation failure during amdgpu initialization may lead to a NULL
pointer dereference.

[Test case]
The driver was loaded, as it can be loaded even on systems without the card,
and the affected path will be executed (a kfd device is created).

[Potential regression]
amdgpu users may have problems with the graphics system.
