x86/kernel: Mark expected switch-case fall-throughs
In preparation to enable -Wimplicit-fallthrough by default, mark
switch-case statements where fall-through is intentional, explicitly in
order to fix a couple of -Wimplicit-fallthrough warnings.
Warning level 3 was used: -Wimplicit-fallthrough=3.
[ bp: Massasge and trim commit message. ]
