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.
