plus: missing breaks.

* arith.c (plus): Add missing break statements to two switch
cases.  One is at the end, where it is not strictly necessary.
The other omission is harmless also and may have been
deliberate, though not commented by a /* fallthrough */.
The other functions with this same pattern, namely minus,
has the breaks.
