    watchdog: wdt_pci: mark expected switch fall-through
    
    In preparation to enabling -Wimplicit-fallthrough, mark switch cases
    where we are expecting to fall through.
    
    Notice that in this particular case I replaced "Fall" with a proper
    "fall through" comment, which is what GCC is expecting to find.
