drm/amdgpu: Queue KFD reset workitem in VF FED
The guest recovery sequence is buggy in Fatal Error when both
FLR & KFD reset workitems are queued at the same time. In addition,
FLR guest recovery sequence is out of order when PF/VF communication
breaks due to a GPU fatal error
As a temporary work around, perform a KFD style reset (Initiate reset
request from the guest) inside the pf2vf thread on FED.
