Subject: [PATCH 4/7] slimbus: messaging: Fix fall-through warnings for Clang

From: "Gustavo A. R. Silva" <gustavoars@...nel.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.
