drm/amdgpu: Fix SDMA TO after GPU reset v3
After GPU reset amdgpu_vm_clear_bo triggers VM flush
but job->vm_pd_addr is not set causing SDMA TO.
v2:
Per advise by Christian König avoid flushing VM for jobs where
job->vm_pd_addr wasn't explicitly set.
v3:
Shortcut vm_flush_needed early.
Fixes cbd5285 drm/amdgpu: move setting the GART addr into TTM.
