Upstream commit cfd6ed4537a9 ("usbip: Fix implicit fallthrough warning")
GCC 7 now warns when switch statements fall through implicitly, and with -Werror enabled in configure.ac, that makes these tools unbuildable.
We fix this by notifying the compiler that this particular case statement is meant to fall through.
