drm/amdgpu: break GPU recovery once it's in bad state(v4)
When GPU executes recovery and retriving bad GPU tag
from external eerpom device, the recovery will be broken
and error message is printed as well for user's awareness.
v2: Refine warning message in threshold reaching case, and
fix spelling typo.
v3: Fix explicit calling of bad gpu.
v4: Rename function names.
