[PATCH 1/9] security: keys: Fix fall-through warnings for Clang

[David Howells]

From: Gustavo A. R. Silva <gustavo...@kernel.org>

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