drm/amdgpu: ignoring unsupported ras blocks when MCA bank dispatches

This patch is used to solve the problem of incorrect parsing of error counts.
When the UE trigger gpu is reset, the driver will attempt to parse all possible ras blocks.
For ras blocks that are not supported by the current ASIC, the driver should ignore this error.
