If ERRSTS indicates that there's no error then we don't need to bother reading the other registers. In addition to making the common case faster, this actually fixes a small race where we don't see an error but we clear the error bits anyway, potentially wiping away info on an error that happened in the interim (or where a CE arrives between the first and second read of ERRSTS, causing us to falsely claim "UE overwrote CE").
