[PATCH 2/2] Revert "drm/amdgpu: No longer insert ras blocks into ras_list if it already exists in ras_list"

[yipechai]

This reverts commit 48e175f7476c6deb7ccf1f10d081322d52830a17.

Xgmi ras initialization had been moved from .late_init to early_init,
the defect of repeated calling amdgpu_ras_register_ras_block had been
fixed, so revert this patch.
