amd64_edac: Reorganize error reporting path
Rewrite CE/UE paths so that they use the same code and drop additional code duplication in handle_ue. Add a struct err_info which collects required info for the error reporting. This, in turn, helps slimming all edac_mc_handle_error() calls down to one. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
