drm/amdkfd: make sure VM is ready for updating operations
When page table BOs were evicted but not validated before
updating page tables, VM is still in evicting state,
amdgpu_vm_update_range returns -EBUSY and
restore_process_worker runs into a dead loop.
v2: Split the BO validation and page table update into two
separate loops in amdgpu_amdkfd_restore_process_bos. (Felix)
1.Validate BOs
2.Validate VM (and DMABuf attachments)
3.Update page tables for the BOs validated above
Fixes: 50661eb1a2c8 ("drm/amdgpu: Auto-validate DMABuf imports in compute VMs")
