Subject: [PATCH] kprobes/x86: Fix fall-through warnings for Clang

[ Upstream commit e689b300c99ca2dd80d3f662e19499bba27cda09 ]

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