[PATCH] drm/amdgpu: tighten gpu_recover in mailbox_flr to avoid duplicate recover in sriov

[wentalou]

sriov's gpu_recover inside xgpu_ai_mailbox_flr_work would cause duplicate recover in TDR.
TDR's gpu_recover would be triggered by amdgpu_job_timedout,
that could avoid vk-cts failure by unexpected recover.
