[Xen-devel] [PATCH] xen/pvcalls-front: mark expected switch fall-through

["Gustavo A. R. Silva" <garsilva@xxxxxxxxxxxxxx>]

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" comment
on its own line, which is what GCC is expecting to find.
