drm/amdgpu: Fix the BO release clear memory warning
This happens when the amdgpu_bo_release_notify running
before amdgpu_ttm_set_buffer_funcs_status set the buffer
funcs to enabled.
check the buffer funcs enablement before calling the fill
buffer memory.
v2:(Christian)
- Apply it only for GEM buffers and since GEM buffers are only
allocated/freed while the driver is loaded we never run into
the issue to clear with buffer funcs disabled.
v3:(Mario)
- drop the stable tag as this will presumably go into a
-fixes PR for 6.10
Log snip:
*ERROR* Trying to clear memory with ring turned off.
