drm/amdgpu/userq: actually validate userq BOs

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: actually validate userq BOs This was supposed to loop over the individual evicted list, as the kernel and always_valid evicted lists were already handled in amdgpu_vm_validate. Without this, BOs that were created and evicted before a userq was made would never end up in an eviction fence rearm. Also add the missing ref to the BO before drm_exec locks and refs it. (cherry picked from commit 18decfc9e8cc0fa70b6de9944cc27a37729edfbd)
