drm/amdgpu: Remove redundant .ras_fini initialization in some ras blocks

2022-03-02T23:40:06+00:00

1. Define amdgpu_ras_block_late_fini_default in amdgpu_ras.c as
   .ras_fini common function, which is called when
   .ras_fini of ras block isn't initialized.
2. Remove the code of using amdgpu_ras_block_late_fini to
   initialize .ras_fini in ras blocks.

2. Function calls inside the modules only use parameters
   passed from xxx_ras_fini instead of ras block instance
   members.
