drm/amdgpu: make err_data structure built-in for ras_manager

(No effect outside the ras_mgr data structure)

Since a new member was added to the ras_err_data data structure,
it becomes unreasonable for the ras_mgr instance to contain this data,
because ras mgr only uses the 2 member information of ue_count/ce_count in err_data.

This patch changes the code err_data into built-in structure members,
making the code directly compatible.
