PATCH 1/1 Input: xen-kbdfront - 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 placed the "fall through" part at the beginning of the code comment, which is what GCC is expecting to find.
