drm/amdkfd: fix vram allocation failure for a special case

Browse source

[ Upstream commit 93aa919ca0 ]

When it only allocates vram without va, which is 0, and a
SVM range allocated stays in this range, the vram allocation
returns failure. It should be skipped for this case from
SVM usage check.
