[PATCH] drm/amdgpu:Check gfx poweron when skip flush_gpu_tlb

[Feifei Xu]

To fix the gpu recovery failed on GFX11 with gfxhub pagefault,
flush gpu tlb after reset on GFX11.
Gfxhub tlb flush need check if adev->gfx.is_poweron set.

Fixes: d0c860f33553 ("drm/amdgpu: rework lock handling for flush_tlb v2")
