[PATCH 2/2] style: do not "break" in switch() after "return"

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Remove this unreachable code. It was found by SunCC, it's found by a
non-fatal warning emitted by SunCC. It's one of the things it's more
vehement about than GCC & Clang.

It complains about a lot of other similarly unreachable code, e.g. a
BUG(...) without a "return", and a "return 0" after a long if/else,
both of whom have "return" statements. Those are also genuine
redundancies to a compiler, but arguably make the code a bit easier to
read & less fragile to maintain.

These return/break cases are just unnecessary however, and as seen
here the surrounding code just did a plain "return" without a "break"
already.
