[PATCH][next] ima: Fix fall-through warning for Clang

[Gustavo A. R. Silva]

In preparation to enable -Wimplicit-fallthrough for Clang, fix a
fall-through warning by explicitly adding a break statement instead
of just letting the code fall through to the next case.

JFYI: We had thousands of these sorts of warnings and now we are down
      to just 13 in linux-next(20210607). This is one of those last
      remaining warnings. :)
