[PATCH wayland] scanner: Reword fallthrough comment to quiet GCC

[Daniel Stone]

GCC 7 now requires an explicit comment noting that case statements
without a break fall through. We already had one of those in the
scanner, but GCC wasn't smart enough to pick it up.

Quiet the warning by making the comment less elaborate.
