drm/amdgpu: Implement unrecoverable error message handling for VFs
This notification may arrive in VF mailbox while polling for response from
another event.
This patches covers the following scenarios:
- If VF is already in RMA state, then do not attempt to contact the host.
Host will ignore the VF after sending the notification.
- If the notification is detected during polling, then set the RMA status,
and return error to caller.
- If the notification arrives by interrupt, then set the RMA status and
queue a reset. This reset will fail and VF will stop runtime services.
