Subject: [PATCH v2 2/2] 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.
