Subject: usbip: Fix implicit fallthrough warning

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.
