drm/amdgpu: Fix resume failures when device is gone
Problem: When device goes into suspend and unplugged during it then all HW programming during resume fails leading to a bad SW during pci remove handling which follows. Because device is first resumed and only later removed we cannot rely on drm_dev_enter/exit here. Fix: Use a flag we use for PCIe error recovery to avoid accessing registres. This allows to successfully complete pm resume sequence and finish pci remove.
