[PATCH RESEND][next] xfrm: Fix fall-through warnings for Clang

From: "Gustavo A. R. Silva" <gustavoars@kernel.org>
Date: 2021-03-05 09:23:56
Also in: linux-hardening, lkml
Subsystem: networking [general], networking [ipsec], the rest · Maintainers: "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Steffen Klassert, Herbert Xu, Linus Torvalds

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.
