[PATCH 3/3] virt: vbox: Use fallthrough;

[Joe Perches]

Convert the various uses of fallthrough comments to fallthrough;

Done via script
Link: https://lore.kernel.org/lkml/b56602fcf79f849e733e7b521bb0e17895d390fa.1582230379.git.joe@xxxxxxxxxxx/

And by hand:

drivers/virt/vboxguest/vboxguest_core.c has a fallthrough comment outside
of an #ifdef block that causes gcc to emit a warning if converted in-place.

So move the new fallthrough; inside the containing #ifdef/#endif too.
